Synopsis:
Following the loss of the Sea Witch, the Sea Devils enter a contest to win a new boat. They must bring back the best prize from their dives, while competing against other teams. The team finds prize after prize, but each is lost before they can return with it to the surface.

Having failed to retrieve anything from the ocean depths, the Sea Devils return to the surface. They then discover that one of the other teams has hijacked the prize boat. They defeat the hijackers and are awarded the boat as a prize.
