HAWAII FIVE-0 is a contemporary take on the classic series about a new elite federalized task force whose mission is to wipe out crimes. The team consists of Detective Steve McGarrett (Alex O'Loughlin), a former Naval officer who returns to Oahu to investigate his father's murder. Steve stays after Hawaii's Governor persuades him to head up the new team. Other members of the team include Detective Danny "Danno" Williams (Scott Caan), an ex-New Jersey cop who is committed to keeping the Islands safe for his 8-year-old daughter and Chin Ho Kelly (Daniel Dae Kim), the former protégé of McGarrett's father who is wrongly accused of corruption and relegated to a federal security patrol. Another main character is Chin's cousin, Kono (Grace Park), a beautiful and fearless native, fresh out of the academy and eager to establish herself among the department's elite.

In this new season, a new governor, Sam Denning (Richard T. Jones) is introduced after the murder of his predecessor, Patricia Jameson. However unlike Jameson, Denning orders new changes to the task force. How will the team copes with the new changes?
