A former San Francisco police detective juggles wrestling with his personal demons and becoming obsessed with the hauntingly beautiful woman he has been hired to trail, who may be deeply disturbed.

When his longtime partner on the force is killed, reckless U.S. Secret Service agent Richard Chance (William L. Petersen) vows revenge, setting out to nab dangerous counterfeit artist Eric Masters (Willem Dafoe). Along with his new, straitlaced partner, John Vukovich (John Pankow), Chance sets up a scheme to entrap Masters, resulting in the accidental death of an undercover officer. As Chance's desire for justice becomes an obsession, Vukovich questions the lawless methods he employs.
