United States Navy officer rank insignia Ted Jackson is a former U.S. Navy frogman who divides his time between twin careers as a deep sea diver and nightclub singer. Ted discovers what he believes could be a fortune in Spanish gold aboard a sunken ship and sets out to rescue it with the help of go-go dancing yoga expert Jo Symington and friend Judd Whitman. Gil Carey, however, is also after the treasure and uses his girlfriend Dina Bishop to foil Ted's plans.
