NEW FACES, EXPLOSIVE CASES! Five-0's past, present, and future are about to collide when a Hawaiian crime wave heats up! With McGarrett (Alex O'Loughlin) leading their missions, HPD's elite team bolsters its roster with new recruits Tani (Meaghan Rath) and Junior (Beulah Koale) to hunt a serial arsonist and a diabolical hacker (special guest stars Randy Couture and Joey Lawrence). As a gang of mob murders sweeps the island, Adam (Ian Anthony Dale) heads up an organized crime unit. Bioweapon exposure and a gunman's bullet threaten to take down Danny (Scott Caan) for good. And while Grover (Chi McBride) faces personal demons, Jerry (Jorge Garcia) teams with a familiar face to stop a terrorist from building a bomb. Hawaii Five-0: The Eighth Season features all 25 intense episodes.
