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, returned to Oahu to investigate his father's murder and stayed 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. Joining McGarrett is Detective Danny "Danno" Williams, a relocated ex-New Jersey cop - a working man in paradise who prefers skyscrapers to the coastline - but who's committed to keeping the Islands safe for his young daughter; Chin Ho Kelly, an ex-Honolulu police detective and former protégé of McGarrett's father who was wrongly accused of corruption; Dr. Max Bergman, the quirky coroner; Chin's cousin, Kono Kalakaua, a beautiful and fearless native; and Captain Lou Grover, who formerly headed Hawaii's SWAT unit. Joining them is Jerry Ortega, a former classmate of Chin's and the Island's local conspiracy theorist. The state's brash FIVE-0 unit, who may spar and jest among themselves, remain determined to eliminate the seedy elements from the 50th state.
