It's the last day for students and staff at Roosevelt High School. The seniors are wild and unruly, setting off pranks on their classmates and teachers. English teacher Andy Campbell (Charlie Day) has his parking spot taken by a student on a scooter, and he is too meek and sensitive to do anything about it. History teacher Ron Strickland (Ice Cube) is the most feared teacher in school. He catches two boys taking a prized bat from the school's cage and replaced it with a computer so they can watch porn. Strickland orders them to put the bat back and leave.
Some of the teachers are worried because they have evaluations later that day that will determine the fate of their jobs. Campbell in particular is worried because he and his wife Maggie (JoAnna Garcia Swisher) are expecting their second child. Campbell gets pranked in his class when students draw dicks on his board. He gets pulled out by guidance counselor Holly Grossman (Jillian Bell) to let him know that some of the other English teachers have gotten canned, so his job might be safe.
