A space ship crash lands on the third planet of a distant solar system, killing all hands except for a young boy named Tang. The rescue ship arrives some 20 years later. One of the crew, a girl named Linda meets Tang and falls in love with him. They are attacked by the native humanoids of the planet and many of them are killed off. Also, the crew encounters many strange beasts on this strange, but somewhat familiar world.

Sheriff Plummer and his men are using their badges to easily rob gold shipments and kill the drivers. Marshal McDowell and his men are looking for the killers. They catch one who is murdered to keep from talking but his killer is identified as Plummer's Deputy. Plummer is still not suspected when McDowell's wife is kidnaped and the outlaws demand the big gold shipment be sent unguarded. So McDowell heads out alone to face the gang with a load of gunpowder instead of gold and only a few trusted Deputies nearby.
