Med school student Teddy Grey ( Milo Ventimiglia ) graduates top of his class from Harvard and joins one of the nation’s most prestigious Pathology programs. With talent and determination, Teddy is quickly noticed by the program’s privileged and elite band of pathology interns who invite him into their crowd. Intrigued by his new friends he begins to uncover secrets he never expected and finds that he has unknowingly become a pawn in their dangerous and secret after-hours game at the morgue of who can commit the perfect undetectable murder. As Teddy becomes seduced into their wild extracurricular activities, the danger becomes real and he must stay one step ahead of the game before he is the next victim.

Teddy joins them in their game, until eventually the group's leader, Jake Gallo, realizes that Teddy is sleeping with his girlfriend, Dr. Juliette Bath, while Gallo would murder people during their secret meetings. Not to mention, when Teddy catches several members of the group in lies, he realizes that what initially seemed like vigilante killings are, in actuality, just innocent people murdered for sport. When Teddy's fiancée arrives to stay with him in his apartment, Gallo, angered by his girlfriend's infidelity, kills his girlfriend for the next game. However, just as they are about to begin the autopsy on Bath (while plotting Teddy's death), Gallo realizes that the gas has been left on in the room, resulting in a massive explosion as one of the group lights a meth pipe, killing everyone (but Teddy who was not in the room). Gallo realizes what is about to happen and survives. Teddy is seen walking away from the explosion. Eventually Gallo manages to kill Teddy's fiancée in what he believes to be the "perfect murder". Upon completing his autopsy report on his murdered fiancée, Teddy is knocked out by Gallo and then is forced to trade verbal barbs with him. Teddy uses some of Gallo's own rhetoric against him in reverse psychology fashion, after which fellow pathologist Ben Stravinsky frees Teddy and together they kill Gallo in exactly the same way that he killed Teddy's fiancée (during which, they commence dissecting a still alive Gallo).
