Synopsis:
The Sea Devils undertake a dangerous mission to help test an atomic bomb underwater. The team becomes trapped under the bomb when the cable lowering it snaps. They escape by diving deeper into an ocean beneath the ocean.

There, they are captured by an exiled alien made of coral. The creature forces the male Sea Devils to perform tasks for his amusement. Each task is completed, and the Sea Devils escape, riding a waterspout back to the surface. There escape comes just in time as the bomb explodes, closing off the inner Earth ocean.
