The SWAT team hunts for a band of criminals re-enacting the crimes of the infamous Symbionese Liberation Army, whose decades-old offenses made local and national news. Seeking expertise on the original crime spree in the 1970s, Luca and his father, Carl Luca, review the files of Luca's late grandfather who worked for SWAT during the era of the original crimes. Also, Hondo experiences discrimination from a fellow officer during a SWAT training seminar for local law enforcement in Arizona.

When the SWAT team is called in to work on their day off to end a hostage situation, they discover one of the captives is a wanted felon. Also, when Hondo saves his sister, Brianna, after she's been roofied at a nightclub, he uses his day off to hunt a serial rapist.
