Steve (Roger Gentry) is leading a mission to Mars. The mission runs into trouble when it reaches the red planet and crashes. The crew of four are stuck on the planet and only have a few days oxygen supply left. They find Mars barren except for a few bizarre monsters.
Finally, they find a cavern inhabited by a Martian collective conscienceness in the form of the Martian Wizard (John Carradine)...
The film is all rather slow though pretty atmospheric. This isn't a standard 1960s science-fiction film, indeed it is all rather psychedelic and at times pretty inventive though it is also a bit dull. Not a great deal happens and the characters are rather annoying. It isn't great and unfortunately isn't terrible enough to be truly entertaining!
