This movie features Lloyd Bridges, Osa Massen, John Emery, Noah Beery, Jr., Hugh O'Brian, Morris Ankrum, Patrick Ahern, Sherry Moreland, John Dutra and Katherine Marlowe. Four men and a woman blast into space on humanity's first expedition to the Moon, a 48-hour journey. A malfunction causes the ship to drift off course and sends them hurtling to Mars. The rocket passes through clouds to land on Mars where they find evidence of a once-powerful civilization, as evidenced by an art-deco wall-hanging of a face, and a backdrop of a building shaped rather like a dynamo. There has been a planetary nuclear war.
