In the Line of Fire

Secret Service Agents Frank Horrigan and Al D'Andrea meet with members of a counterfeiting group at a marina. The group's leader, Mendoza, tells Horrigan that he has identified D'Andrea as an undercover agent, and forces him to prove his loyalty by putting a gun to D'Andrea's head and pulling the trigger. When the gun just clicks, Horrigan then shoots and kills Mendoza's men, identifies himself as an agent, and arrests him.
