Kenny is out riding when he spots a wild rabbit. He chases it into an abandoned mine and there's a cave in. Cheyenne and his Sioux friend Char riding by split up as Char returns to his village and Cheyenne heads to Gainesville. A posse spots Cheyenne who tells them he has not seen the boy. The sheriff's posse then finds Char leading the boy's horse. Their prejudices and his answers don't add up so he is arrested. The sheriff was forced to shoot and kill the drunken son of the local Sioux Chief Sleeping Bear and Char's brother a day or two earlier. In town Char is spotted by his friend Cheyenne who goes to the jail to vouch for his friend. The sheriff doesn't buy his story and locks Char up. Meanwhile the boy's hysterical mother has to be calmed as well as the restless townspeople. Elsewhere, the local saloon owner Peg shows an interest in Kenny's disappearance.
