The tale of Rupert, a lovable trained squirrel who unknowingly helps a family of vaudeville performers who are down on their luck.

A mysterious, meteorlike object has landed in a small California town. All clocks have stopped. A fleet of glowing green UFOs hovers menacingly over the entire globe. The Martian invasion of Earth has begun, and it seems that nothing-- neither military might nor the scientific know-how of nuclear physicist Dr. Clayton Forrester (Gene Barry)-- can stop it.
