The SWAT team tries to determine the next diamond dealer to be robbed by a group of highly organized thieves executing heists across downtown Los Angeles. When Hondo is emotionally affected by a suspect's death during the case, he seeks comfort from his mother, Charice. Also, while Street worries that Luca, his SWAT training academy instructor, has a personal vendetta against him, Chris contemplates an unorthodox relationship offer from the new woman she's dating.
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.
