On its last legs, Monogram released this picture on the coattails of the highly successful DESTINATION MOON (1950). The chief difference between the two features is that this time color is used--a first for sci-fi films. A group of scientists crash-land on the red planet and are held
prisoner. The Martians plan to copy the US spacecraft and build their own invasion fleet. Of course, a love-stricken Martian girl helps the Earthlings escape.
