Dr. Royce, a scientist with an expertise that can be used in the underwater detection of ships, is lured by enemy agents and his girlfriend to defect to a foreign power. McGarrett is both helped and hindered by a federal agent named Merrill Carson in trying to prevent Royce from leaving the island with the enemy agents, even as Dr. Royce gradually realizes that he is more a prisoner than a willing defector.

When they arrive at the location, however, McGarrett is wearing a solid light blue suit with a black or dark blue tie. See more
