An elementary school class is reunited for a party. Ethan Haas throws a party to ask his girlfriend to marry him and she ends up breaking up with him in front of everyone.

Ethan tries to get Kat to fix him up with one of her friends and Nicole has to deal with her husband becoming good friends with her ex-boyfriend, who's now working on her house.

Ethan and Kat interject themselves into a blind date and some of the gang gets together over Duncan's old band when they re-unite for a gig in a bar. Things go awry when he asks Nicole to attend.

After Holly presents a news story on the air concerning Richie crashing into a convenience store during a fight with a bee, the rest of the class gathers there, as well.

Richie returns home one final time to get his things, only to find his wife there, who finds out there's another woman in his life. Ethan uses Kyle as a buffer for Kat at a party.

Old school games abound when Lena confesses to Nicole that she has yet to be intimate with Richie, who, in turn, tells Duncan and convinces him to convince Richie to take the plunge.

Nicole and Yonk are both on diet, but then Yonk catches her eating with Duncan. Kat starts having real feelings for Benjamin. Lina and Richie host a dinner party. But Lina's Moroccan Chicken is not to anyone's tastes.

A Valentine's Day snowstorm strands the class away from the ones they love, and leaves some of them with interesting ways of trying to re-unite.

Duncan agrees to let Yonk buy lunch in an effort to get him out of the house so Nicole can pack her things and get ready to move out. Ethan stumbles across a secret and deliberates telling Kat.
