Roy, Dale, and Pat come across an old prospector who was attacked and blinded by a pair of outlaws. When they learn that the outlaws stole some ore samples that the prospector recently found in a nearby mine, Roy offers the old man the use of his dog Bullet to help find more ore in the mine. Through the course of their investigation, they discover that a friend is one of the outlaws, out to kill the old prospector and anyone else who gets in their way of collecting on a big strike.

Dale gets tricked by some con artists into selling them her ranch. The swindlers then promptly sell her ranch to a newcomer into town who unknowingly gets swindled as well. Realizing that something is running afoul, they work together to help Roy and the sheriff to bring them to justice.
