Hawaii Five-O: Cocoon

SYNOPSIS

The series pilot, which originally aired as a two-hour TV movie, is re-edited as a two-part episode of the series. In the opening installment, a U.S. intelligent agent, a friend of McGarrett's, turns up dead on a Honolulu beach. McGarrett, knowing the man didn't swim, decides to investigate the death as a homicide. Five-O gets no cooperation from the Feds, making McGarrett suspicious. His probe eventually leads to a mysterious ship, which is in dock for repairs. Going undercover as a member of a repair crew, McGarrett discovers a futuristic-looking chamber.
