Astronauts (Lloyd Bridges, Osa Massen, John Emery, Noah Beery, Jr., and Hugh O'Brien) blast off to explore the moon on. Because of craft malfunction and some fuel calculations, they end up landing on Mars. On Mars, evidence of a once powerful civilization is found. The scientists determined that an atomic war destroyed most of the Martians (who suprsingly look like humans). Those that survived reverted to a caveman like existence.

Backfire (1950): A war veteran, aided by his resourceful nurse, is on a quest to prove his pal innocent of murder. Deadline at dawn (1946): A gangster's sister lies dead. All clues point to sailor Bill Williams. He has mere hours to prove that he is innocent.
