Nicholas "Oz" Oseransky (Perry) is a nice dentist living in suburban Montreal. His new next door neighbor, Jimmy "The Tulip" Tudeski (Willis), is a hit man hiding out from a dangerous Chicago crime family. Despite their differences, Oz and Jimmy have one thing in common: someone's trying to kill them both.
For Jimmy, avoiding a couple of hired killers is child's play. But for Oz, it's a whole new ball game. To stay alive, they're going to have to stick together - Jimmy with his cunning and cold-blooded accuracy and Oz with his dental tools.
