In 2065, the World Aquanaut Security Patrol (W.A.S.P.) keeps the peace and performs oceanic rescues. From Marineville, their ultra-sophisticated island headquarters, Commander Sam Shore gives orders to Stingray, an atomic super-sub piloted by stalwart Captain Troy Tempest (voice: Don Mason) and his sidekick, 'Phones'. Their adventures bring them in contact with a number of previously unknown man-like civilizations living in caverns beneath the ocean floors, mainly the Aquaphipbians. Monstrous and hostile, the warlike race is led by a villain named Titan, who wants to exterminate all of the 'surface dwellers' on the land above.
