Fiona, wanting to impress them as well as gain their friendship which would lead to popularity, asks them if she should throw a party; Marisol enthusiastically agrees. Throughout the episode the three discuss who should be invited; Fiona reveals that she invited Imogen, much to Katie and Marisol's dismay. During the party, the party-goers play truth or dare. Owen dares Fiona to drink an entire bottle of alcohol. Imogen, aware of Fiona's past as an alcoholic, jumps to her defense by bluntly stating, "Fiona can't drink that because she's an alcoholic."
Marisol then harshly says to Imogen to not joke about something as serious as alcoholism. Fiona, wanting to change the subject, says that she does not want to vomit at her own party; she suggest that instead to play a senior prank. The prank was that all party-goers will wrap tin-foil around every object in the Degrassi Cafeteria. While the prank is being committed, Imogen decides to explore the school. Marisol follows after Imogen to keep an eye on her. While Imogen is in the theater, listening to her mp3 player, the doors are locked.

Marisol convinces Fiona to persuade Imogen to take all of the blame. Fiona goes over to Imogen's house and convinces her to take all of the blame, she then reports back to Marisol and Katie. Marisol then admits to Fiona and Katie saying that she was the one that locked Imogen in the theatre to avenge the fact that she called Fiona an alcoholic. Fiona, feeling remorseful of what happened to Imogen, decides to persuade Marisol and Katie to confess with her to Mr. Simpson. Marisol agrees and says that because it is important to Fiona, it is important to her and Katie. Later, Marisol and Katie are in principal Simpsons office with Fiona, ready to confess.
