Synopsis: A plane arrives in Hawaii with 300 passengers aboard, including a tour group of 40. After everyone has left the plane, however, a stewardess discovers that one remaining passenger is dead, the victim of a stabbing with a thin instrument of some kind. Then a woman is discovered dead in a tropical park with a similar wound. Because the victim on the plane turns out to have been a CIA agent, McGarrett contacts Jonathan Kaye in Washington, and learns that the killer may be a mysterious hit man known only as “Raymond.” With little information about either the killer or his intended victim, McGarrett assigns officer Sandi Welles (seen in the previous season’s “Loose Ends Get Hit”) to go undercover as a guide with the tour group from the plane, hoping that she can discover something.
