Buster McHenry (Kiefer Sutherland) works as an undercover agent for the Philadelphia Police Department. He is attempting to flush out a corrupt officer. McHenry's investigation hits two complications. The first occurs when he gets arrested while trying to stop a carjacking. He distracts the suspect with a beer bottle and assaults an officer. The second occurs when he participates in a robbery of a jewelry store to retrieve $6 million in diamonds. During the course of fleeing the crime scene, an ancient Indian spear is stolen from an Auction House and Buster is wounded.
