After the SD-6 finds out that another terrorist organisation was attacked at the same time as them, Sydney and Dixon are sent to Las Vegas, and later Moscow, to try to find something that will bring SD-6 closer to identity of The Man.

Vaughn presents Sydney with a moral dilemma that includes Sloane's ill wife, Emily, in order to fulfill the mission whose outcome is an unpleasant surprise to everyone. SD-6 goes after Will when he comes too close. Meanwhile, Francie is dealing with her broken heart.

Francie is having a rat problem in her house and gives an inspiring speech about catching them which gives Sydney idea how to catch Khasinau. She and Vaughn set up fake transaction for a Rambaldi artifact with Sark, but their job is compromised when Sloane sends SD-6 agents to steal the presumed second vial. Meanwhile, Will learns the truth about his kidnapping and Jack Bristow has no option but to help him.

While Sloane is desperate to buy few more days for his wife, Will, with a help of Jack, sets up a meeting with his contact "Deepthroat" in Paris. As the luck would have it, Sydney and Dixon will be there at the same time trying to steal a very important document from Khasinau aka "The Man" and his right hand, Mr. Sark, who was just recently in the custody of the SD-6.

Sloane must take a difficult decision in order to get to the Alliance's council. After being captured by Sark, Tippin is tortured by a Taiwanese would-be dentist to extract secrets. Sydney, who has to beware her colleague Dixon, assist her father trying to save Tippin. However, after losing Vaughn when the lab exploded, she is in for a surprise...

Sydney finds herself face-to-face with her long-lost mother, Irina Derevko, whose intentions for her daughter are made chillingly clear. However, Sydney manages to escape and rejoin Jack and Will in their escape from Taiwan. After arriving back in Los Angeles, Sydney continues her search for Vaughn, not knowing if he is dead or alive after being swept away by a wall of water in Taipei. Will's life is forever changed when he learns the truth about SD-6 and Sydney's life as a double agent. Also, Dixon must decide whether or not to inform Sloane of Sydney's suspicious activities. But Jack intervenes and covers for Sydney who later finds Vaughn who helps her try to track down her mother Irina who's searching for a Rimbaldi artifact called 'the Bible.'

After turning herself in to the CIA, Irina won't communicate with anyone - except her daughter. Sydney refuses to cooperate, until a mission goes awry and crucial information falls into the wrong hands. Now, against Jack's wishes, Sydney must face Irina and find out what She knows.

Sydney must travel to Sri Lanka to outwit Sark in order to find a crucial piece of Intel from a computer disk that she recovers from Rabal.

And Jack tries to convince Sydney that Irina is setting the stage to betray them and will go to any lengths to prove it.

Jack's decision to sabotage Sydney's last mission while pinning it on Irina not only brings him closer to his daughter - it sends his ex-wife to death row. But his foolproof plan begins to unravel when Vaughn begins to put the pieces together - and Sydney makes a startling discovery about her childhood.

Sydney's fury at Jack's present betrayal and past sins leads her father to a desperate act to prove his love for her. Meanwhile, Vaughn - after enlisting Will in a seemingly benign CIA request - learns that a mission He and Sydney engaged in could have disastrous consequences for their health.

As Vaughn's life hangs in the balance, Sydney has no choice but to turn to Sark for help in securing an antidote for the virus. But when Sark demands She help him to kill Arvin Sloane in exchange for his assistance, Sydney faces a decision that could expose her as a double agent.

Sark's alliance with SD-6 suddenly puts Sydney at risk of being exposed as a double agent. She has no choice but to cooperate with his plan, until his alliance with Sloane sends several nuclear weapons into the wrong hands. Now, only Irina holds the key to unraveling Sark's agenda - and She refuses to cooperate.

Still trapped in hostile territory in Pakistan, Sydney, Jack, and Irina continue their search for the missing nuclear warheads held by PRF's leader Gerard Cuvee. After several misadventures, they arrive at Cuvee's stronghold, only to be betrayed by Irina. Back in the USA, Vaughn wants to mount a secret rescue mission to Pakistan before Kendell authorized the Indian army to launch an air strike on the facility with Jack and Sydney held captive inside. Meanwhile, Sloan decides to pay off his unknown blackmailer.

Backed into a corner, Sark cuts a desperate deal Sloane using Sydney to recover a state-of-the-art surveillance system. But when the plan goes awry, SD-6 sends Marshall with Sydney on her next mission... giving the CIA no choice but to extract the op-tech specialist. Now Sydney faces the consequences of "waking up" Marshall - and possibly destroying his life in the process.

When Sydney learns that Marshall has been kidnapped, she struggles against a heartless Sloane to bring Marshall back whom is being tortured by the same Taiwanese torturer Dr. Lee "Suit and Glasses" to uncover the code for the top secret ECHELON security system whom tries to stall for time. Sydney and Dixon are instead sent to Ho Chi Minh City, Vietnam to recover the hard drive for ECHELON. Meanwhile, Kendall and the rest of the CIA frantically tries to prevent SD-6 from gaining access to ECHELON... and Jack realizes that the only one who can help them is Irina.

Sydney and Vaughn reach a crossroads as they try to turn a professional relationship into a personal one during a mission to recover an experimental gyroscope. Meanwhile, Jack struggles to outwit the persistent SD-6 security expert, Ariana Kane, as she tightens the noose of suspicion around him of being Sloan's blackmailer.

The entire world of 'ALIAS' is turned upside down. Sloane disappears mysteriously and Anthony Geiger becomes the new head of SD-6. As the Bristows struggle to keep their secrets safe and stay one step ahead of Geiger, Will and Francie make a startling discovery of their own while Francie prepares to open her new restaurant. After an airborne mission, Sydney uncovers crucial information that could shut down SD-6 and bring down the entire Alliance.

When a young CIA agent dies, suspicion immediately falls on her parter and lover, agent Jim Lennox. But after Sydney rescues Lennox from captivity, She trikes up an instant connection as they discover shared wounds - realizing They've both lost someone they love to the job. Yet even her judgment is thrown when Vaughn and Jack discover that Lennox was pursing a technology that allows people to change their appearance. Now Sydney must ask herself: is this the real Jim Lennox - or is his double?

Sydney finally has the opportunity to leave the CIA for good, but a startling phone call from Sloane, combined with the kidnapping of a brilliant mathematician, brings her back into the fray.

When Sloane gets his hands on a terrifying Rimbaldi weapon that causes internal spontaneous combustion, Sydney must turn to a betrayed and hurt Dixon for help. But when her ex-partner refuses any assistance, She has no choice but to carry out the mission herself. When Sydney is captured, Vaughn must persuade Dixon to help the CIA rescue Sydney from an Afghan warlord's camp.

When Sydney learns that Vaughn is under investigation for being a double agent, Jack and Irina forge an unlikely partnership in their attempt to get their daughter out of the CIA for good. Kendall learns that Sark and Sloane are attempting to get their hands on a Rambaldi manuscript detailing the works of the human heart, so he sends Jack and Irina to Bangkok to learn more, and then to Panama to capture Sloane. But Irina betrays Jack and escapes from custody... this time for real.

Following her betrayal, the CIA try desperately to track down Irina Derevko. Their trail on Derevko leads them to Stuttgart and closer to Sark and Sloane, even as Sloane contemplates giving up his quest to complete Rambaldi's work in order to stay with his wife, Emily.

When the CIA intercepts a secret message, Sydney discovers that the life of Neil Caplan, the mathematician still held captive by Sloane and Irina, may be in danger from the most unlikely source: his wife Elsa whom Jack has arrested, forcing Sydney to try to clear Elsa's name by going on her own mission to Moscow and Spain to try to rescue Neil Caplan. Meanwhile, Sloane becomes obsessed with finding out who accidentally killed Emily, and Sark makes contact with the Francie impostor to locate the person responsible... by using Will to infiltrate the CIA satellite surveillance systems.

As Dixon struggles with the death of his wife, He refuses to take time off from work until Sloane is brought to justice. But Sydney worries that Dixon's repressed rage could cause more harm that anything Sloane could do.

Having woken up in Hong Kong, with no memory for the last two years (!), Sydney returns to Los Angeles to try to piece together the last two years of her life and discovers the fates of her friends and family: Vaughn has married thinking that Sydney was long dead; Marshall is having a baby with CIA tech expert Carrie Bowman; and Dixon is now the new division head of the L.A. office branch of the CIA. Sydney also learns the shocking fates of Jack and Sloane; the former is in CIA custody for communicating with Irina whom still is in hiding, while the latter is living in Switzerland under house arrest in exchange for co-operation with the CIA. Sydney is granted temporary CIA clearance on a case that may help her regain her memory and she meets a new enemy group called The Covenant.

Sydney's search for her past leads to an imprisoned Sark, but their Q&A is cut short when he becomes the ransom for a pair of abducted CIA scientists by the Covenant, whose kidnappers may be tied to the murder of his father. Meanwhile, Jack contacts an old friend of sorts for info on Sloane's new world-peace project in Switzerland. Also, Vaughn makes a decision about his future as an operative for the CIA.

Also, Sydney accompanies Vaughn and his wife, Lauren, as they meet with Sloane to ask for a favor.

Sydney discovers a link to her missing two years in the form of Simon Walker, the dangerous leader of a group determined on retrieving deadly biological weapons. Meanwhile, Vaughn struggles with his own feelings of jealousy and longing while Sydney is on her mission, aware of the pressures his job is putting on his marriage to Lauren.

Meanwhile Lauren's search for Lazarey's murderer leads her closer to discovering the connection to Sydney, and Sydney begrudgingly is assigned as Sloane's CIA handler.

Jack takes drastic measures to ensure that the NSC never finds out the truth about Sydney's murder of the Russian diplomat Lazarey. But, his actions place a heavy strain on Vaughn's marriage, as Lauren gets closer and closer to the truth about Sydney. Meanwhile, Sydney agrees to go on a mission with Sloane in order to thwart plans to obtain the operating system to a deadly weapon, and she discovers an unlikely ally in the hunt for her missing two years.

But with only hours to spare before she is forced to undergo a radical surgery to recover her memories, they must put together an extraction team, headed by freelance operative Brill. Meanwhile, Lauren faces an impossible choice: side with the NSC who she wants to believe is doing the right thing, or with her husband in their rescue of Sydney.

After making a shocking discovery of a severed human hand in the desert that belonged to Lazarey, the Russian diplomat she murdered while working as a brainwashed assassin for the Covenant, and who may in fact be alive, Sydney agrees to submit to an experimental procedure conducted by an eccentric doctor, named Dr. Brezzel, designed to retrieve her lost memories. But while Jack and Vaughn look on, Sydney's mind proves surprisingly resistant to letting her remember her missing time... and the process of recovering it could end up killing her. Meanwhile, Lauren makes a great sacrifice of allowing herself to get tortured and beaten up in order to make her alibi believable to Lindsey after helping breaking Sydney out of NSC custody. Also Sloane finds himself boxed in by an unlikely enemy, that of Mr. Lindsey, who wants to see Sydney Bristow eliminated permanently.

The identity of the mysterious "St. Aidan" forces Sydney to pull a stunned Will Tippin out of witness protection for help in finding Lazarey to clear her name. But the pursuit sends the two old friends on a collision course with Allison, the Francie impostor who ruined both their lives. Meanwhile, a jealous Lindsey arrests Jack and Vaughn as conspirators in Sydney's escape from NSC custody. Sloane, still under pressure from Lindsey, puts a plan in motion to eliminate Sydney, and Dr. Brezzel has an unpleasant run-in with Sark whom is also looking for Sydney.

In this episode, Sydney finally learns the shocking truth about her missing two years from an unlikely source: FBI Special Officer Kendall. Kendall whisks her away and talks to her from the privacy of an airborne 757 jet. According to Kendall, Sydney was captured by the Covenant after her fight with Francie/Allison, held captive in Russia for over a year and brainwashed to become an assassin. But Sydney only pretended to be brainwashed and contacted Kendall who became her contact and handler, thus giving him information about the Covenant and about their quest for Rambaldi artifacts. Sydney also staged the murder of Andrian Lazarey, and then deliberately had her memory erased to prevent the Covenant from knowing about secrets she had learned about Rambaldi's findings.

Jack contacts a mysterious woman, that of former KGB agent Katya Derevko, Irina's older sister, to help him free Sydney and Vaughn, whose plane has crashed inside North Korea while seeking to find a defecting Russian scientist, named Leonid Lisenker, whom Sark is trying to kill before turning himself to the CIA.
