Nicholas “Oz” Oseransky (Matthew Perry) is a nice dentist living in suburban Montreal. His new next door neighbor, Jimmy “The Tulip” Tudeski (Bruce 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.
