S.W.A.T. Show Summary

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.
