During a large storm one night over Rhode Island, a Colombian cartel plane is struck by lightning in mid-flight and crashes. Zooming in the wreckage, the cargo is revealed: psychoactive toads, which get into the hands of teenagers and begin drug fanaticism among the middle and high schools. Loisand Peter become concerned when the toad-licking problem arises in school. After finding a toad in Chris' pocket they suspect him, but then they discover that Meg was holding the toad for one of the popular kids in the hope that doing so would secure her a date to the Winter Snow Ball. Peter recalls his nervousness when he first asked his high school crush, Phoebe Diamond, to the prom. Later, Lois and Peter decide they need to do something to protect their kids from this drug problem. So, Peter talks with Meg's principal about it and arrives at school the next day as "Lando Griffin", an undercover student, no relation to Meg Griffin.
Before long, Peter (as Lando) actually succeeds in convincing the kids at James Woods High that it's not cool to lick toad. Meg, seeing an opportunity, tells the cool kids that Lando has asked her to the Winter Snow Ball, which immediately increases her popularity. Meanwhile, Peter seems to be enjoying his "high school" experience and persona a little too much. In fact, when Meg shows up at school on the day of the big dance, she is stunned to learn that "Lando" is, in fact, going to the Winter Snow Ball with Connie D'Amico, a member of the popular clique.
Lois can't believe Peter's preposterous behavior until Brian explains that Peter has transferred his feelings for his old crush, Phoebe, onto Connie. Against Lois forbidding Peter to go to dance, he sneaks out to go to the dance. Lois encourages Meg to go to the dance by herself. When Peter (as Lando) and Connie are about to be crowned king and queen of the Winter Snow Ball, Peter uses the opportunity to tell the crowd that Meg was really his first choice as a date for the dance. This gets Meg lots of the attention she was seeking. "Lando" then drives recklessly off into the night, never to be heard from again. The next day, the news reports that "Lando" died when he went off Dead Man's Curve. Although no body was found, the police "decided not to ask questions and just let everyone get on with their lives". Meg becomes cool at school and the yearbook is dedicated to Lando. The song "Don't You (Forget About Me)" plays, as the episode fades away, and ends.
