Les Tremayne

The first spaceship to Mars, presumed lost, is found & brought to Earth. Only two of the crew are alive. One is unconscious due to an attached alien growth, the other is traumatized, with amnesia. The amnesiac is interrogated into remembering what happened. Those in charge learn of the terrible dangers awaiting anyone venturing into the Martian ecosystem. Mars scenes are tinted red in Cinemagic.
