This tense espionage drama takes place in Hawaii, where Dr. Jim Ransom (Lex Barker) investigates sabotage carried out by pro-Japanese Fifth Columnists who want to destabilize the islands in November, 1941 -- just before the attack on Pearl Harbor. Jim is hampered by racist labor specialist Roger (Glenn Langan), although Roger's wife, nurse Ann (Mari Blanchard), helps Jim find the truth behind the explosive attacks on vital sugar plantations.
