When fast-talking lawyer Jeff Winger (Joel McHale) finds his degree has been revoked, he is forced to go back to school at Greendale Community College. Hoping to score points with a pretty coed, he invents a study group and invites her to join it. Imagine his surprise when she's not the only one who shows up for help with Spanish from the "board-certified tutor" he proclaims himself to be. Though his command of the language is anything but good, the members continue to meet and end up learning a lot about themselves.

Jeff is forced to make a decision when the date he's scheduled with a hot statistics professor clashes with Annie's Day of the Dead party.

Greendale students, including Pierce, ingest a biohazardous substance at a Halloween party that turns them into zombies; some must save themselves and the school when they are locked in with infected students.

When an anonymous personality test that Britta runs on the group indicates that one of them is severely troubled, she asks Jeff to help her identify the person.

On Halloween, Pierce accidentally locks himself in his panic room, forcing the gang to search through his house to find the code that unlocks the door.
