Saving his friends from a problem in their submarine, and taking them safely to the surface, Superman has returned to his identity as Clark Kent. Now they spot another submarine. It’s a German U-boat, and its shooting at them.
The tiny submarine is soon boarded, and those low down, filthy Nazi’s take over. Heavy handed, and bullying, the brutes have no compassion as they push our heroes around.
Pretending to be hurt, Clark takes advantage of the distraction to dive under the waves as Superman. What will he do to turn the situation around? Superman flies the captured U-boat off to an American Naval base, and takes Jimmy along to get medical attention. What about Clark? Can you find him before you go? Sorry Lois, he just doesn’t have time for that… you’ll have to find him yourself. Up… Up… and away!
