The SWAT team participates in a joint task force with the FBI when a car bombing has ties to a terrorist group planning an attack in Los Angeles. Also, a tragedy from Deacon's past gives insight into the origins of his faith, and Luca and his brother, Terry, battle over a new family revelation.
Los Angeles S.W.A.T. lieutenant Daniel "Hondo" Harrelson 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 these 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.
