In the sweltering heat of a future Los Angeles stricken by both a scorching heatwave and a ravaging drug war, the city’s streets have become a volatile combat zone. Amidst this chaos, Lt. Mike Harrigan, a tough and streetwise cop, leads a squad dedicated to maintaining the peace and dispensing justice.

This agency, led by the enigmatic Peter Keyes, is also intent on tracking down the perpetrator of these violent acts. They believe they are hunting a threat unlike any the city has seen before, one that is not human and possesses advanced technology and weaponry. As more details come to light, Harrigan becomes determined to solve the puzzle and stop the merciless killing spree, setting the stage for a confrontation that could unravel the very fabric of his reality.
