A wounded archaeologist crawls into the camp of three kindhearted cowboys. When the cowboys bring him to a nearby trading post, he's murdered after he lets slip a secret about a hidden cave. Investigating his death, Ken and his friends encounter a land dispute between a pair of neighboring ranches, an arrogant German baron and a mysterious shack that houses a great secret.
