After surviving a sneak attack on himself and fellow feds Jimmy and Gene as they transport Mafia boss Raymond Manta out of a Mexican jail, FBI agentJeff Douglas becomes an unwitting pawn of the White Hand mafia cartel. The White Hand lies to Jeff and says that his family is being held hostage and he has to help them smuggle a huge drug shipment to get them released unharmed, Jeff is forced to turn one-time courier for the White Hand, whose leaders are Manta and four others—Helmut Vitch, Milt Kowalski, Russ LaFleur, and Hansel Lee. In truth, the cartel had already murdered his wife and two young children, and planned to kill Jeff after he succeeded in delivering their drugs. The drugs are delivered and the White Hand sets Jeff up to be killed in a car bombing in Las Vegas, but Jeff's instincts kick in and he is only slightly injured in the blast, and the cartel thinks he is dead and gone. Jeff then finds out that his family was wiped out and breaks down. A short time later, the FBI wants to get him back to work, but Jeff has begun planning his revenge against the White Hand. Officially censured but unofficially aided by concerned agent Megan, whose mother was raped and murdered years ago, Jeff steals some FBI files and kicks off his cartel extermination campaign by killing Vitch in Las Vegas, at Vitch's casino. In New Orleans, Jeff sabotages LaFleur's liquid-heroin deal with a factory fire, and then at LaFleur's night club, Jeff finishes him off in full view of a satellite hook-up watched by Manta and Kowalski at their hide-out. Kowalski does not enjoy killing and is angry that Manta's brutal murder plan is disrupting their business, which begins to anger Manta in turn. After that, Jeff kills Lee in his heavily guarded mansion in Seattle. After Megan arrives to speed up Jeff's getaway, the couple is apprehended by local cops, and then ambushed by Manta's men. Although Megan is captured and taken away in a helicopter, Jeff momentarily flees. Angered by Kowalski's accurate descriptions of him as a sadistic creep, Manta shoots and kills Kowalski at his complex, but endures a savage beating from Jeff who is able to rescue Megan. Under arrest at FBI headquarters, Manta says it's not over by a long shot. Manta grabs a gun, and in an effort to disarm Manta, Jeff plows into Manta and sends him through a window. As a result, Manta takes a fall to his death, which completes Jeff's mission to wipe out the White Hand cartel.
