Master thief Marcus Webb leads his crew in robbing the Castellano crime family's mansion, stealing $40 million in bonds and compromising hard drives containing evidence of decades of criminal activity. When the family discovers the theft and demands return of the materials, Marcus instead leaks the evidence to law enforcement and media, triggering federal investigations that destroy the Castellano empire. The crew successfully liquidates the bonds and disperses with millions each, while Marcus declines future offers to work for the weakened family, maintaining his principles as a thief who steals only from criminals.
