S1·E10 Running Ghost

Sully ends up badly beaten and partially paralyzed following a run in with buffalo hunters who were hired by the railroad to clear the buffalo and Indians out of the planned train path. As Dr. Mike, Cloud Dancing and the kids fight to help Sully regain the use of his legs, a con man who's passed himself off as an advance man for the railroad is in the process of swindling the townsfolk out of the deed to their property. Sully recovers and Dr. Mike unmasks the con man's plan thereby saving the townsfolk's property.
