The Dreams' first gig: a sweet-16 party.

During Valentine's Day Tony realizes that he and Sam only have four months before Sam has to return to Hong Kong. He writes a special song for her and also decides to propose to her, so that they can stay together. The gang has doubts about whether she should accept.

Tiffani takes on the role of student principal for a week. Sam tries to tutor the gang in physics for their upcoming midterm. The gang decides to have a cut day during the midterm week while Tiffani is in charge.

In order to get the California Dreams a gig, Sly goes on a date with an overweight girl that he used to tease. He finally does get a conscience and starts to feel bad about using her. Meanwhile, a poem that Mark wrote for a crush goes from Mark to Lorena to Jake and then to Tony, making everyone think that the poem was written for them.

Sam creates a video letter to send back home to her Uncle Tze Tze to show him that she has made friends in America. The episode is full of flashbacks from previous episodes.

The gang decides to rectify the thing that they most regret doing or not doing during their time at high school. Sly's biggest regret is never telling Lorena that he has feelings for her. He tries to fix the problem by sending her anonymous love letters. Tiffani's biggest regret is being mean to a boy that asked her out freshman year. While, Sam and Tony regret not competing in the dance contest. Mark regrets letting the school's gym teacher get to him and Jake regrets not playing the bagpipes in public.

While trying to impress Sara, a girl that he likes, Mark decides to drink at Lorena's graduation party. He's too drunk to drive home, but does, and that leads to Sara ending up in the hospital and Mark ending up in jail. Meanwhile, Jake and Tiffani have to finish a class project or they won't graduate. The gang also finally get their diplomas from the Principal.

The band's amp blows and Lorena offers to buy them a replacement. The only catch is that she want's to be co-manager of the band alongside Sly. When she and Sly start arguing, it costs the band gigs. The new amp that Lorena buys blows the wiring at her loft and Jake and the guys try to fix it.
