At the all-night graduation lock-in party, graduates set out to fulfill their unfinished business; for many, it's their last chance to live their high school dreams, but things inevitably take a turn for the senior class of Sherman Grove High.

A last-minute arrival at grad night causes a stir as students create videos predicting where they will be in 20 years; Deanna vows to tell Fig her true feelings while Roni's friends try to convince her there is another reason why Oz is pulling away.

As karaoke commences, Roni makes a huge announcement but is topped by the revelation of a bigger secret; Bryce begins to lay the groundwork for his seduction of the gym teacher's wife; Christian urges Melinda to come out of her shell.

The stroke of midnight means it's time for Midnight Madness, a crazy game that ends up amplifying the bad blood between Deanna and Cassie; Roni, Alexis and Lyssee plot their revenge on Oz; Melinda makes a plan to acquire more alcohol for the party.

The night takes a turn as '80s-themed jello wrestling pits students against each other; Fig finally gets to talk to Roni; Deanna confesses her feelings; Christian and Melinda sneak out to steal alcohol; Bryce discovers the key to Mrs. Lewis' heart.

As half of the students fall asleep, Nino's music livens things up; Melinda misjudges a moment between her and Christian; Cassie helps Deanna go through an emotional and cosmetic makeover; Bryce coerces Mrs. Lewis to sneak away.
