Daniel "Hondo" Harrelson, a Los Angeles S.W.A.T. lieutenant, is assigned to lead a highly skilled unit in the community where he grew up. Torn between loyalty to the streets, where the cops are sometimes the enemy, and allegiance to his brothers in blue, he strategically straddles the two worlds. Hondo encourages his team to rely on communication and respect over force and aggression, but when a crisis erupts, these unflinching men and women are prepared to put their tactical training to the test.

The squad scrambles to track down a cold-blooded sniper terrorizing Los Angeles; Tan finds himself questioning his leadership abilities; Powell and Alfaro compete in a classic game of S.W.A.T. tag.

Tan finds himself on a one-man mission to save his new love interest and her journalist co-workers when mercenaries take over a black-tie correspondents' dinner; Hondo and Nichelle return home to find their house trashed.

The team faces a prison hostage situation, only to be thrown into deeper danger when a bomb explodes, freeing maximum-security prisoners from their cells, including someone with a personal grudge against Hondo.

A blackout throws the city into chaos, forcing the team onto the streets for an emergency patrol day, which quickly escalates when Hondo and team uncover a terror threat.
