An innocent man visiting a friend in New York City becomes embroiled in a dangerous series of events after being mistaken for the very man he has come to the city to see in director Paul McGuigan's labyrinthine murder mystery. Upon arriving at the empty apartment of his old friend Nick, the unassuming Slevin (Josh Hartnett) is troubled to hear the voice of his missing friend's next door neighbor Lindsay (Lucy Liu) expressing concern as to Nick's safety and whereabouts. When Slevin ventures into Lindsay's apartment only to be greeted by the uninviting fist of a thuggish mob henchman, he quickly realizes that Nick is indeed in grave danger. Soon summoned by the big boss and accused of being the deeply indebted Nick, Slevin's attempts to prove his identity are foiled by the fact that his wallet had been stolen upon arrival in the city. With time running out and a complex plot to assassinate one of the city's most powerful crime bosses slowly coming into focus, the arrival of a notorious hit-man named Mr. Goodkat (Bruce Willis) forces Slevin to step up his desperate search and reclaim his identity before he's forced to pay a debt that could cost him his life.
