Shot Caller. Jacob Harlon (Coster-Waldau), a successful financier, is sent to jail after a drink driving accident. In order to survive the cutthroat prison environment, he joins the Ayran Brotherhood prison gang. Upon release, Harlon is a changed man, and must placate his no-nonsense parole agent, and an LA County sheriff, at the same time as repaying the debt to the gang who looked after him inside, who want him to arrange an illegal arms deal. He has to comply if he wants to keep his family safe from vengeance.
