The Phantom Planet

“It Begins Where Others End! On the Moon!”

Captain Frank Chapman (Dean Fredericks) wants to learn why spacecraft keep vanishing near a drifting asteroid, and his own ship is pulled down to its surface to find out. The planet's strange atmosphere shrinks him to the size of its people, who hold him as a stranger among them. William Marshall puts Frank in the company of Liara (Coleen Gray), a woman of the planet who begins to see him as more than a prisoner.
