Corrupt and violently psychotic cop "Whip" O'Leary (Don Stroud) is making a bid to become the city's principal drug dealer, but first he must eliminate the competition. He does so by hiring hit man Zack Ramses (Scott Baio), a former green beret and explosives expert, to blow them up. During one hit, Zack very nearly kills a young girl, Jaime (Shannon Bruce), a violation of his "no kids" rule. He rescues Jaime and, pretending to be a simple good samaritan, allows her to stay at his apartment until she finds a place to live. But when O'Leary discovers Jaime has a videotape that could incriminate him, he sends his crew of crooked cops after her.

At home in his artist's studio, Zack is developing an affection for young Jaime, despite his cold exterior. Jaime, too, is warming up to Zack, until she discovers his true profession. She flees his apartment, only to be spotted by O'Leary's men. Though Jaime escapes, O'Leary shakes down Zack's agent, Gail (Charlene Tilton) for the hit man's whereabouts, then captures both Gale and Jaime in order to draw out Zack and the videotape. Zack meets O'Leary, offering to exchange the girls for the tape; O'Leary, of course, would rather have both. A firefight ensues, during which Gail and Jaime escape and all but Zack and O'Leary are killed. Zack then reveals that he has wired himself with explosives, and for the coup de grace blows them both to kingdom come
