Hondo and his team close in on the gang that has been committing robberies using SCUBA gear.

Following a training exercise with S.W.A.T. officers from another division, Hondo and Street find the dead body of officer Frank Crane with the words ""Kill S.W.A.T."" pinned to his chest. The murder of Crane is the forerunner of a series of attempts to wipe out S.W.A.T. by brothers Mike and Simon Bishop and their fanatic sister-in-law, Joanna, who is convinced that the death of her husband was the result of S.W.A.T. ""brutality.""

Two officers go undercover to catch drug dealers.

Mel Lang and Ralph Costa have served sentences in prison after being framed by one Carl Rigby and arrested by Hondo Harrelson. When S.W.A.T. is called upon to assist police in evicting heavily armed brothers Will and Johnny Brewer from a home taken over by Rigby, Lang and Costa plan to execute Hondo and Rigby and create evidence pointing to the Brewer Brothers.

Runaway teenager Kathy Benson, seeking shelter in the warehouse, calls police when several men break in. Before fleeing the scene, Kathy gets a clear look at the leader, Gregg Colby, a prominent citizen and former U.S. Senator, attempting to solve his money problems by stealing from his own warehouse, collecting the insurance, and later selling his own ""stolen"" merchandise. He pretends to offer assistance to police investigating the case so that he can silence the only eyewitness, Kathy.
