Actor-comedian-talk show host Keenen Ivory Wayans stars in his own action thriller screenplay about a war hero who becomes the fall guy in a frame-up. During the Persian Gulf War, U.S. Marine Sgt. James Dunn (Wayans) refuses to shoot a young shepherd, struggles with a superior officer, and winds up with a murder conviction. Sentenced to death in a military prison, Dunn is rescued from a prisoner-transport bus and selected for a special covert "Black Sheep" unit commanded by Lt. Col. Grant Casey (Jon Voight). Casey offers Dunn freedom if he will aid their battle against corrupt industrialist Donald Bickhart (Robert Culp). During the dedication of a Los Angeles medical research building, the First Lady is assassinated, and Dunn discovers that he has been set up as the trigger-man. Caught in a conspiracy, Dunn relies on his own survival skills and expert military training to elude those in pursuit, including corrupt Army superiors plus police and government agents. To clear his name and expose the real killers, Dunn kidnaps Dr. Victoria Constantini (Jill Hennessy), an eyewitness who made a videotape of the assassination. Now he has the evidence he needs and an uncooperative hostage, but after a $10 million bounty is announced, his situation gets even more desperate as he finds himself chased through the streets of Los Angeles by an immense money-hungry crowd hoping to collect the reward. The freeway filming of this chase featured an unprecedented stunt -- 16 stunt people simultaneously hit by 20 cars. Another stunt required a leap from a 45-story building.
