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.
