Med school student Teddy Grey graduates at the top of his class from Harvard and joins one of the nation's most prestigious pathology programs. There, a rivalry develops between a group of interns and Teddy. They invite him into their group, which entertains itself with a secret after-hours game at the morgue of who can commit the perfect undetectable murder. Eventually the group's leader, Jake Gallo, realizes that Teddy is sleeping with his girlfriend, Juliette Bath. When Teddy catches several members of the group in lies, he realizes that what initially seemed like vigilante killings are, in reality, innocent people murdered for sport.
