Detective Steve McGarrett, a decorated Naval officer-turned-cop, returns to Oahu to investigate his father's murder and stays after Hawaii's Governor persuades him to head up a new team: his rules, her backing, no red tape, and full blanket authority to hunt down the biggest "game" in town. Joining McGarrett is Detective Danny "Danno" Williams, a newly relocated ex-New Jersey cop is committed to keeping the islands safe for his 8-year-old daughter. Chin Ho Kelly, an ex-Honolulu Police Detective, is wrongly accused of corruption and relegated to a federal security patrol. Chin's cousin, Kono Kalakaua, is fresh out of the academy and eager to establish herself among the department's elite. The state's brash new Five-0 unit may spar and jest among themselves, but they are determined to eliminate the seedy elements from the Hawaii's sun-drenched shores.
