The Last Call

When a routine operation turns into a deadly ambush, Daniel 'Hondo' Harrelson is left fighting for his life after taking a sniper's bullet meant for one of his own.

As 20-Squad struggles to survive the aftermath, the team discovers the attack was no accident. Someone leaked SWAT's tactical routes - and the betrayal may come from inside the department itself.

While Hondo battles between life and death in the ICU, Los Angeles' SWAT family reunites around him. Dominique Luca returns from command, Jim Street and Christina 'Chris' Alonso come back leading their own Long Beach SWAT teams, and Robert Hicks prepares for a war against whoever targeted his officers.

But the deeper they investigate, the darker the truth becomes.

And when sealed letters written by Hondo are discovered - goodbye letters meant for his wife, daughter, team, and family in case he ever died in the line of duty - everyone is forced to face the possibility that their leader may never come home.

In a city built on loyalty, one bullet threatens to destroy everything.
