The plot? Illegal sea dump of USN’s ‘dud’ missile arsenal; sacrificing aged sub, naive captain, geriatric robot crew and traitor, rogue robot Shirley. J-Circ Shirley, returned in error from Japan, is found to be last ‘tapper’ on earth. A 3-way, undersea submersible life and death contest ensues: Japanese and Chinese samurai versus US Holy Buck Corp. Winner take Shirl.
