Hawaii Five-0

CBS | 9:00 pm

Seeking justice for a murdered friend who was a CIA agent, McGarrett (Alex O’Loughlin) allows himself to be captured by those he suspects are responsible in the Season 9 premiere "Ka ‘Owili ‘Oka’l," which means "Cocoon" and is a retelling of the pilot episode from the original 1968-80 series. As McGarrett endures a sensory deprivation tank to find the killer, Tani (Meaghan Rath) debates whether to tell him about the murder weapon she found at Adam’s (Ian Anthony Dale) house.
