A Nut for Marineville

Shore gets off on the wrong foot with Professor Burgoyne, the 'boffin' sent to Marineville to develop the new super missile needed to destroy an indestructable craft heading toward Marineville. The Professor is presumed dead when his lab explodes but he calmly reappears to announce the success of his work. Armed with the new super missile, Stingray sets off to destroy the enemy sub.
