Synopsis:
A missing space capsule containing an astronaut crashes into the ocean near the Sea Devils. Dane and Biff dive after it in order to save the astronaut, but discover that the capsule contains an alien composed of water.

The alien is part of an invasion force, who have taken the astronaut captive. His mission is to scout the Earth as a possible target. The Sea Devils battle the creature, but it is far more powerful. Also it possesses the ability to read their thoughts. Finally, the team lures it into the path of an active volcano. The intense heat causes the alien water-being to turn into steam and prevents it from summoning the invasion force.
