It's the start of the school year. For their upcoming anniversary, penniless Spinner wants to get the perfect present for Paige. His idea: get her the perfect locker, since the one she has been assigned she considers in purgatory. In Spinner's mind, Hazel has the perfect locker, but it will take some swift maneuvering to get Hazel to give it up. Emma has thoughts other than school on her mind. With Spike almost ready to give birth and with Spike and Snake's recent marriage, Emma has been thinking about her biological father, Shane McKay. Spike has told Emma nothing about Shane, except that she wants Emma to have nothing to do with him as he deserted them. All Emma vaguely remembers is meeting Shane once in a hospital when she was three years old, Emma remembering that Shane was wearing a doctor's uniform. Emma does whatever she needs to to locate Shane and know her biological dad.

Through Snake's alumni database, Emma does locate her biological father, Shane McKay, at an address in Stouffville. When she arrives at that address, she sees that it is a medical institution and that Shane, mentally disabled, is a patient. Emma's first thought is that her mother is a heartless woman who deserted Shane during his time of need. Emma's view of her mother changes when she learns the full story and why Spike did not tell her the truth about Shane. But Spike may be in trouble when Shane escapes from the institution and wants to see his old girlfriend. Meanwhile, Spinner managed to get Hazel's locker for Paige, who deems it not to be the perfect locker. In her mind, Jimmy has the perfect locker. Jimmy, knowing that Spinner will probably do anything for the locker, makes a deal with Spinner, one not only that Spinner will find embarrassing to do, but one that Spinner does not realize will put Paige in a bad light.

Feeling like a wallflower, Manny decides to try out a new overtly sexual fashion style at school despite it contravening the school's code of conduct. Her attempt at looking sexy has the affect that she is hoping. The person who shows the most interest in her is her long time friend J.T., who is a bit confused about these new feelings he has for his friend. But he has to work fast to attract her attention as others are also showing interest in her. With her new look however is also a new self-absorbed attitude. Meanwhile, Craig, Marco, Jimmy and Spinner have formed a yet unnamed band. Joey has allowed them to use his garage as a practice space. Joey is vicariously reliving his teen-aged years through the band much to Craig's chagrin.

A group of the kids go to the beach for the day. Despite stating that she will no longer be his cover as his girlfriend, Ellie, who doesn't really get along with most of the others but especially Paige, decides to go along on Marco's invitation. Also along as the chauffeur is Paige's openly gay older brother, Dylan. Dylan, attracted to him, suspects Marco may be gay. Marco, also attracted to Dylan, is not ready to come out, especially to his supposed best friend Spinner, who is openly homophobic. Marco goes out of his way to hide his sexual orientation. This includes showing an interest in team sports and going on a date with an unsuspecting Hazel. Meanwhile, Archie is staying at the Jeremiah's temporarily as he has a cold and Spike does not want him to infect Jack. Beyond ruining his weekend with Ashley as the unexpected chaperon, Craig thinks that Snake's symptoms may be a manifestation of something beyond the common cold.

Spinner does not react well to Marco coming out to him. Without initially actually outing Marco to the general populous, Spinner does whatever he can to freeze Marco out of his life. Spinner spreads the news amongst their closest group of friends, all of who think Spinner is acting like an idiot. Marco will need all the support he can when he learns first hand what it's like to be gay in an intolerant society. A specific incident pushes Marco further in the closet. Meanwhile, Snake's initial medical diagnosis is possible leukemia. He tries to make light of the situation, which affects Emma more than anyone. Regardless of the final diagnosis, his actions, in part because of the possible diagnosis of leukemia, benefit Degrassi as a whole.

Snake's illness is causing a strain on Emma and Sean's alone time. Sean, feeling lost without Emma's support, has thoughts of his old troubled life. He starts to gravitate toward trouble-makers Jay, Alex and Towerz. A fight with Emma over their lack of time alone together turns Sean's thoughts into reality. Sean does whatever he feels he needs to be to be accepted, an act which ends up hurting Emma. Meanwhile, J.T. is hanging out with the in crowd - his new friends - leaving Toby in the lurch. At a sleep-over at Toby's, an embarrassed J.T. has a wet dream over Liberty, which Toby lords over him as blackmail in also being able to hang out with the in crowd.

She has an interview for what she considers her dream co-op job working for Caitlin at the radio station doing stories on social causes, but she's up against "perfect" Paige for the sole position. These stresses end up having a physical manifestation, which Ellie, ashamed, feels she needs to hide. Ellie gets an unexpected source of support.
