Street's partner, officer Rob Duran, is killed in the premeditated police assassination by two brothers bent on revenging their father's death. That and subsequent police killings serve to shape the psychology of Lt. Dan ""Hondo"" Harrelson's newly formed Special Weapons and Tactics team, ""S.W.A.T."" The team's task is to combat high risk, contemporary, urban crime as a strike force. The team consists of James Street, David ""Deacon"" Kay, T.J.. McCabe, Dominic Luca, and Harrelson.

While the S.W.A.T. unit has their hands full foiling both a heist and a kidnapping, a beautiful but nosy reporter arrives at police headquarters, spending a few days with S.W.A.T. members to write an investigative piece.

Zealous student activists, inspired by a non-aggression philosophy class Street attends, steal a cache of guns and take control of a chemical plant to protest bio-terrorism, threatening to blow it up unless they receive a million-dollar ransom.

While leading the team in the rescue of several women being held hostage by two known killers in a massage parlor, Hondo is grazed by a bullet across his temple.
