When a veteran police officer who served with Hondo in Vietnam lobbies to fill in for ailing "Deacon" Kay, Hondo thinks he's the right man for the job - until urban combat dredges up jungle-warfare memories for the embattled vet, triggering a nervous breakdown that risks jeopardizing the entire team.
Street's partner, officer Rob Duran, is killed in the premeditated police assassination by two brothers bent on revenging their father's death.

""S.W.A.T.""'s first assignment is an acid test of their ability to survive as individuals and as a team. Their rigorous training is literally a fight against time.
