In this new psychological horror-thriller from Tate Taylor and Blumhouse, a lonely woman befriends a group of teenagers and decides to let them party at her house. Just when the kids think their luck couldn't get any better, things start happening that make them question the intention of their crazy host.

18-year-old Addison Schacht, a Jewish high-school senior in Washington D.C., responds to the essay question, "What are your best and worst qualities?". He explains he has only bad qualities, as illustrated by the events of his senior year. They include collecting offensive jokes; dealing drugs to his classmates; and insulting teachers, fellow students, and his girlfriend's mother. But his classmate is killed, and he begins to investigate the death.
