Description
New crimes, new criminals and new corruption confront the elite federalised task force known as Hawaii Five-0 in the action-packed series featuring the rugged enforcement team whose mission is to wipe out the crime that washes up on the islands's sun-drenched beaches. Season Two starts with a stunner- Detective/Lieutenant Commander Steve McGarrett (Alex O'Loughlin) finds himself behind bars, accused of murdering the Governor. The action accelerates with new leads in the killing of McGarrett's father. And things go from hot to explosive in cases that include Kono (Grace Park) being suspended from the force, the arrest of Chi Ho (Daniel Dae Kim) at the Russian consulate and the kidnapping of Danno's (Scott Caan) young daughter in a bizarre revenge plot. Join the Five-0 team for all 23 episodes of high-velocity, crime-busting action.
