The Zigra "space woman" creates a gigantic earthquake ("magnitude 18 no less") and they learn of Zigra's past history, advancing in science and destroying their planet. Searching out a new home, Zigra found Earth and orders the "earth creatures" to surrender the Earth. While speaking with Earth, Tom declares the Zigra woman is crazy. In anger, she puts the men in a hypnotic state. Kenny and Helen take action, successfully using the ships console to escape. Enraged, Zigra orders their death. He sends the woman to kill the children. After a close call on the surface of the water, Gamera saves the children and their fathers from Zigra.
