HAWAII FIVE-0 is a contemporary take on the classic series about a new elite federalized task force whose mission is to wipe out the crime that washes up on the islands' sun-drenched beaches.  Detective Steve McGarrett, a decorated Naval officer-turned-cop, returns to Oahu to investigate his father's murder and stays after Hawaii's former governor persuaded him to head up the new team: his rules, no red tape and full blanket authority to hunt down the biggest "game" in town.
