Nathan has gone to Las Vegas with his girlfriend Marnie and baby, Nathan Junior, with the express aim of using his super powers to defraud the casinos. Unfortunately, he gets caught and is led off to prison after making an unsuccessful phone call to Simon - or Barry as he calls him.

Whilst Kelly has trouble convincing people of her new power, the skills of a rocket scientist and Curtis finds his new gift, the ability to change sex useful when pursued by the police, the group learns that Nathan has gone to Las Vegas to use his super-power to cheat the casinos. He is replaced in the team by ladies' man Rudy, an old flame of Alisha, who has the ability to twin himself - somewhat unwittingly - when stressed. This incurs the wrath of pick-up Tanya who believes he is two-timing her and who gets her revenge by killing Charlie, the girl she saw Rudy kissing, and framing him for the murder. Fortunately the second Rudy comes to the rescue after Tanya is accidentally killed and once more the misfits find themselves burying two bodies and hoping to get away with it.

Banned from athletics for drug use Curtis sees the opportunity to still compete as his new gender swap identity Melissa, whilst falling for fellow runner Emma. Emma is bi-sexual and is drawn to both Curtis and his alter ego Melissa but, with only Simon let into the secret, Curtis/Melissa becomes the reluctant object of the sexual attentions of Shaun, Rudy and running coach Mark, who spikes Melissa's drink at a party and tries to rape her, getting a rude shock when Curtis returns. Eventually Curtis is forced to admit the truth to the other misfits and, having saved her from Mark's predatory actions, to Emma.

In his alter ego as Super Hoodie Simon saves comic book fan Peter from a mugging. Later Peter recognizes his protector from his voice and the boys become friends, Simon explaining his destiny to become his future self by dying whilst saving Alisha. Peter, obsessed with his hero, uses his sinister gift to stop this - he draws cartoons in which the events come to pass in reality - and the pair have a climactic fight after Peter has abducted Alisha, though his comic strip reveals that he knew the outcome. Shaun meanwhile discovers Rudy's ability to clone himself whilst Kelly learns that Seth is still carrying a torch for the girlfriend whose death he caused when he was a drug dealer.

Elderly Jew Friedrich Hirsch travels back to 1930s Berlin to kill Hitler but fails and the Nazis use his mobile phone technology which alters history so Germany wins the war and present day Britain is under Nazi control, and none of the misfits know each other. Kelly and Simon are reluctant conscripts whilst Shaun, with Alisha, his unwilling girlfriend, is right hand man to odious Captain Smith. Seth, his ability to give and take super powers an asset to the Nazis, is imprisoned but Kelly and the other misfits spring him, leading to a shoot-out.

Kelly is accidentally body-swapped with a coma patient. Rudy gets anger management therapy.

After a one night stand Rudy loses his most prized possession and begs Simon for help to get it back. Curtis's power malfunctions, trapping him as Melissa.

Having relieved Curtis of the power to change sex Seth instils in him the power to reanimate the dead and bring his girlfriend back to life,as a result of which Seth dumps Kelly. After Curtis has brought back to life a dead cat which savages its owner the gang knows that something is wrong as the born again corpses have a taste for blood,attacking the living and turning them into rabid zombies,including a group of cheer leaders who are rehearsing in the Community Centre. Seth is forced to kill his girlfriend as she prepares to go for him,making him realise that he loves Kelly. Unfortunately the misfits have to kill the cheer-leaders to save themselves and,with them,yet another probation supervisor who was also infected.

The misfits have to face the ghosts of people they killed after a medium brought them back.

After Alisha was tragically murdered in last season's final episode, and Simon traveled back in time to when he sacrificed his life to save hers, Curtis and Rudy continue their community service. Seth returns to pick up Kelly's belongings, as they have decided to move to Africa after a visit where Kelly realized she could use her power to deconstruct land mines. Two new offenders join the community service team: Jess, who has X-ray vision, and Finn, who is a telekinetic. The new offenders quickly realize something is not right. Rudy, Curtis, and Seth (and eventually Jess and Finn), have been infected with some sort of virus after a badly hurt man, with a briefcase handcuffed to him, stumbles into the community center and collapses at their feet. The group becomes so obsessed with obtaining the briefcase, that they're ready to murder each other over it. Finally, as the group tries to get the briefcase from Finn on the roof, the hurt man lunges for it and falls to his death, ending the virus. The new probation officer finally arrives, and is creepy and, possibly psychotic. Finn goes home, and we see that he has a girl bound and gagged in his flat.

When the misfits model for a sculpture class for the blind, Curtis and Rudy both fall for student, Ally, but both are rejected as her guide dog picked up the power of telepathy in the storm, and is conveying their weaknesses to her. Rudy discovers Sadie tied up in Finn's flat and lets her go. Finn explains that following the storm, Sadie picked up the power to control him using violence, but he loves her and does not want to leave her, hence his actions. Sadie counters by saying that she was only curing his slobbishness. Seth agrees to take Sadie's power from her, but in doing so, splits the couple off as they fed off each other's bad points. Both homeless Finn and Rudy move into the Community Centre, where Curtis falls for alluring probation trainee Lola, and Jess is attracted to handsome barman, Alex.

Finn is confused when stepmother Lisa tries to seduce him and even more so when Mike,the man he believed was his father,says Finn is not his son after all. Curtis makes headway with Lola but Jess is annoyed when Alex ducks out of a date. A third Rudy,a violent criminal just out of jail,turns up,frightening the gang with his violent talk and taking over the other two Rudys. After he has got Jess to admit to an attempted suicide after a boy dumped her he attacks Greg but is himself killed by Jess in order to release the other Rudys.

Finn and Rudy have problems over sharing their illicit room in the centre but,after Rudy has been banished to a room full of slugs,decide they miss each other. Lola tells Curtis that ex-boyfriend Jake was violent to her and gives Curtis a gun to threaten him. During a fight the gun goes off,killing Jake but when Curtis discovers that Lola is an impostor he briefly resurrects him and learns that,due to the storm,Lola became a man-hater turning men against each other. However Jake must be killed again to prevent him becoming a zombie. Curtis locates Lola,who now has another boyfriend,whom she plans to use to destroy Curtis,aiming to kill them both and say they shot each other but after she has shot him Curtis briefly comes back to life as a zombie and kills her before shooting himself.

Using old photographs Finn tracks down his real father,Dan,who has terminal cancer but is being kept alive by his daughter Grace,using the power she got in the storm. Dan tells Finn that he is in pain and wants Grace to let him die but she is unhappy when Finn confronts her with her father's request,saying she does not want to be alone. Finn assures her that he will always be there for her. Finn also shadows Alex,believing him to be gay as he keeps meeting other boys. Jess refuses to believe it and has a date with Alex,who kisses her but stops short of sex. However Alex tracks down a particular young man and makes a very bizarre demand of him.

Rudy takes Jess,Finn and Alex to a party held by his drug-loving friend Richard,where they discover they have the number of their sexual partners indelibly written on their foreheads. Richard is cowering in a cupboard,terrified of 'the White Rabbit',an apparent mutant. Bored with the party Finn and Rudy gate-crash a funeral where Rudy talks to the enigmatic Nadine,who rushes away mysteriously at midnight. Following her he is pursued by the giant white rabbit,which has just killed a girl but he escapes and gathers the boys together in time to rescue Jess from the rabbit,helped by a party-goer called Abbey. Next day Alex shows Jess why they cannot have sex. His penis was stolen by a transgender man.

Abbey sticks around at the Community Centre,claiming to be on community service when Greg questions her presence. She meets Tara from an ante-natal class who does not want her baby and transfers it to Abbey. However Abbey initially wants to keep the child,admitting that she lost her memory in the storm and wants something to make her feel she belongs. When Tara returns though Abbey feels sorry for her and reverses the process. Alex locates James, the transgender man who took his penis and tracks him down to a karaoke club, where the other misfits are amazed to see the threatening Greg sing a sensitive song. James gives Alex back what is his. Nadine turns up to see Rudy but rushes away again and when he follows her he discovers that she is a nun.

Rudy is perturbed that the nuns try to prevent him from seeing Nadine and,along with Abbey and Finn - who have just had sex - rescue her from the convent. However Alex's new-found masculinity has made him sexually selfish and Finn argues with him since he has cheated on Jess. Being confronted by anger which stresses her out unfortunately unleashes Nadine's special power - the ability to summon the Four Horsemen of the Apocalypse,which she does despite herself. The misfits are attacked by the horsemen and,although Finn uses his special power to save Abbey,Nadine sacrifices herself to make them disappear for good,leaving Rudy heart-broken. Alex is also stabbed and rushed to hospital.

Alex recovers from his operation and is followed home by Emma, a woman who tells him that his donor, Neil, had the power to rid people of their super-powers through having sex with him, and persuades him to rid her of her unwanted gift, the ability to cause accidents. He reluctantly complies. Back at the Centre Finn meets Lucy, one of a group of Scouts, who seems attracted to him but the group are in fact Satanists who force him to join them as an agent of the devil and commit demonic acts. When holy water fails to cure there is only one solution - Alex takes him from behind, which lifts the curse and saves Jess's life but lands him on Community Service. Meanwhile Rudy 2, against the advice of the original Rudy, joins a self-help group for those possessed of super-powers . Its leader, Maggie, is an elderly lady who knits the future, in Rudy's case a jumper which foretells that he and his friends will become super-heroes.

Rudy is shocked to see his father Geoff (whom he had told he was at university) having sex publicly with another woman, Tina. Later, in company with Jess, Rudy sees Geoff threaten Tina and on a further visit they see him cleaning blood from the floor and burning her clothes. Determined to get to the truth Rudy goes for a drink with Geoff, who explains that, following the storm, he has the power to clone himself (like Rudy, though Rudy keeps quiet about that) and there is a bad Geoff, who has not killed Tina but stolen her money. Jess and Rudy help the good Geoff to restore Tina's money to her and, after the bad clone has tricked Geoff's wife Pat into having sex with him, they overpower him. The balance restored, Rudy tells his parents Jess is his girlfriend, thus dispelling their suspicion that he was gay. Abby finds a purple scarf with an enticing smell, which leads her to a girl called Laura, with whom she hits it off whilst at the support group Rudy 2 meets Sam, who claims he can fly - rather like one of the figures on Maggie's sweater - and Tim, who believes he lives in a violent computer game.

Abby begins an affair with Laura, whom she sees as her soul-mate so she is shocked when she learns that she is actually Laura's imaginary friend from her childhood and that Laura's power, given her by the storm, was to create Abby - who previously did not exist. Laura is scared by this and rejects Abby, who feels depressed. However the two girls combine to get rid of Scary, the bogeyman Laura feared as a child and they remain friends. Greg, having seen Finn being 'exorcised' by Alex, mistakenly believes the boy is gay and makes advances to him - which almost results in the death of yet another supervisor though Greg, feeling ashamed, agrees to back off whilst Rudy is saved from a mugger by flying super-hero Sam.

After Rudy 2 goes missing the others encounter a befuddled old man who, from his tattoos, is clearly a geriatric version of the clone. Seeking answers to how he got that way the original Rudy, accompanied by Finn, goes to the support group but gets little help. Then Rudy discovers a young man threatening the elderly fellow and calling him Mr Johnson before trying to kill him. The youngster was originally an old chap called Mr Johnson and, following the storm, he received the power to swap ages with people - in this case Rudy 2 - so he can marry his young nurse. Rudy forces him to redress the balance and restore his clone before getting closer to Jess.Meanwhile Alex is reluctant to use his power on Stuart, whose unfortunate talent is to end up literally in the closet when he denies that he is gay, but he does give him good advice.

To take his mind off Jess ditching him Rudy 2 takes Finn to the support group where he meets a girl called Leah but when they go on a date she fails to recognize him. Following a call from her he visits her but ends up a prisoner in her 'virtual' flat. After the storm she acquired the ability to turn real life into a computer world, downloading herself into her friend to ensnare Finn, whom she wants to inhabit her virtual world with her. To further put Finn off Jess Rudy 1 takes a photo of her on the toilet but it accidentally gets posted on the global Internet. However the gang put differences aside when, helped by mysterious electrician Helen, they rescue Finn, who ultimately persuades Leah to sample reality. Rudy 2 starts to romance Helen while Rudy 1 ends up dating Jess.

As part of the community service the team help out at a centre for terminally ill young people, organized by Karen. Finn befriends Ben, who admits that he is only feigning illness for the attention but after Ben has been hugged by cancer victim Lucas he kills himself whilst Lucas appears to be in remission. Lucas then hugs Finn, who, like Ben, attempts suicide but is saved by the others. It becomes apparent that Lucas's power is to temporarily extend his life at others' expense and the gang persuade him that he must end it all to save future victims. Alex has a run-in with gay Hayley, who puts a curse on him when he refuses to help her retrieve lost keys whilst Maggie gives Rudy 2 another jumper, showing Helen and himself as a couple and Karen as another super-hero.

Rudy 2 tells Rudy 1 that he wants them to live separate lives so he can be with Helen and, along with Abby, throws a party to celebrate their 'birth' days. Alex brings along Sara, the latest person whom he has relieved of their power but unfortunately he takes an ecstasy tablet, unaware that this will reverse his power so, after sex with Sara, she has taken on all the bad powers Alex has removed from others and in the end one of Sara's new powers saves the gang from her. Rudy 2 is pleased to meet his trio of super-heroes from the jumper, Helen who uses electricity to devastating effect, Karen who can become invisible and Sam, who can fly. They come in handy saving Rudy when Tim, who inhabits the computer game world, goes haywire and tries to kill him. Jess is less thrilled though when Maggie's latest knitwear shows her holding a baby.

The gang discover that their community service is over and begin to contemplate life after the orange jumpsuits.
