Bonanza - Season 4 Episode 11 Gallagher's Sons

Hoss helps Charlie and Will (Charlotte and Willomina), two young girls who just lost their father. They go on a journey to find their only nearby relative, Aunt Cloe. Charlie takes with her a stolen sack of money that her father gave her and tries her best to lose Hoss. Four bandits show up looking for the loot Charlie has. In the end, Hoss finds out about the stolen money and talks the girls into giving it back. He puts them in dresses and sends them off to Boston on a stage, telling them they did the right thing and will probably get the money back as a reward for helping capture the bandits!
