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 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.

When a crew of violent eco-terrorists abducts the teenage son of an energy company executive, the team must untangle the kidnappers' twisted motives before carrying out a high-stakes rescue mission; Hondo's involvement in a shooting draws outrage.

When a spree of brutal stash house robberies spills into Los Angeles, the team joins with the sheriff's department's gang unit to unmask a violent crew who leaves no witness alive.

Following a string of violent home robberies, the team rushes to stop a crew targeting elderly victims; Hondo's longtime friend and former Marine squad leader Danny Wright turns to Hondo for help when his daughter goes missing.
