When a young heiress, Juliette Carlton, is kidnapped for ransom, Hondo and the SWAT team go on a citywide search to bring her home before she is harmed. Also, the team worries that Mumford is moving too fast when he announces he’s getting married for the fourth time.

A fake 911 call puts Hondo and the SWAT team on the hunt to stop a white supremacy group from executing bombing attacks on local communities. Also, Street’s relationship with his recently paroled mother, Karen, jeopardizes his career, and Jessica is thrown a curveball by her colleague, Michael Plank, president of the police commission. Hondo’s father, returns Daniel Harrelson, Sr. 1st.

The abduction of Luca and Street’s neighbor sends the SWAT team in pursuit of a home invasion crew targeting domestic workers to gain entry into upscale homes. Also, the SWAT division prepares to help Mumford mark a major career milestone.
