The kids of New Directions go head-to-head in their annual boys vs. girls mash-up competition using the music of the movies. Santana's snooping results in two shocking discoveries. Will's weekly assignment for New Directions is to choose aspirational songs from their favorite movies, and he pits the boys against the girls in a Glee Club mash-up competition. Snowed in at their New York apartment, Santana continues to ruffle her new roommates' feathers. When her snooping reveals two shocking discoveries, it leads to speculation about one cohabitant, and elicits a difficult confession from another. Meanwhile, Finn tries to locate Emma; Rachel, Finn and Marley each make risky confessions with varying degrees of success; and a secret about Brody is revealed. The glee club's latest assignment is to choose a song from a movie and the members of New Directions sing the hit series' landmark 500th musical performance with their rendition of the "Animal House" anthem "Shout." Meanwhile in New York, Santana makes herself at home in the loft a little too quickly for Rachel and Kurt's comfort.
As everyone recovers from Will and Emma's wedding, the Glee Club members are tasked with performing their favorite movie songs.
