A.P. Bio

Jack Griffin (Glenn Howerton) is a Harvard philosophy scholar who loses out on his dream job and goes to work as a high school Advanced Placement biology teacher in his hometown of Toledo, Ohio. He quickly makes it clear he will not be teaching any biology, however, and, realizing he has a room full of overachieving honor roll students at his disposal, decides instead to use the kids to enact revenge on his rival and take the job that is rightfully his. Eager to prove that he is still king of the castle, Principal Durbin (Patton Oswalt) struggles to control the force of nature that is Jack Griffin.

When Jack leaves his class unattended, a student gets injured, landing Jack in "teacher jail"; a teacher's union representative sets her sights on Durbin; the students are excited about a substitute teacher until they find out it's Helen.

Jack puts his students on a new revenge mission; Helen, Principal Durbin's secretary, relentlessly tries to get Jack to make something for the annual bake sale.

When Jack gets into a petty dispute with the student council president, the situation escalates much too far; Stef sells makeup at school as a side business.

Jack reluctantly agrees to go out on the town with Mary, Stef and Michelle; his superiority complex proves difficult for the women to overcome; principal Durbin feels threatened when Helen fills in for him on the school's morning announcements.

When Jack is attracted to a student's mother at a parent-teacher conference, he feigns interest in her son; a group of parents complain to principal Durbin when they notice a piece of controversial student art from Mary's class.
