Nick, however, is lured into taking one final score by his fence Max (Marlon Brando). The job, worth a $4 million pay off to Nick, is to steal a valuable French scepter, which was being smuggled illegally into the United States through Canada but was accidentally discovered and kept at the Montreal Customs House.Max introduces Nick to Jack Teller (Edward Norton), an ambitious, albeit foolhardy, thief who has infiltrated the Customs House and gained access to information regarding the security by pretending to be an intellectually disabled janitor named Brian.

One of the janitors stumbles upon Jack as he is working and realizes that he is not really Brian, but Jack locks him in a closet. Meanwhile Nick fills the enormous in-floor safe containing the scepter with water before inserting and detonating a depth charge to blow off the door.
