 Jimmy "The Tulip" Tudeski, a mob hitman-turned-informant, ratted on the mob and put his life in jeopardy. Now he has moved to suburban Montreal, ostensibly to make a new start. His next-door neighbor is mild-mannered, unhappily married dentist Nick  Oz  Oseransk. Nick recognizes Jimmy from the newspaper stories about his mob testimony, and that s when Nick s simple, boring world turns upside down.
