The Predator returns, this time hunting the streets of Los Angeles for his prey. The alien has decided to take the feuding, drug-dealing gangsters who are threatening to overrun the city as trophies, but when it starts taking out the police as well, tough cop Lt Mike Harrigan and partners Danny Archuleta and Leona Cantrell set out on its trail. But they must also contend with special agent Peter Keyes, who seems to know what happened to a mercenary patrol in the South American jungle.
