We see all 4 Cartwrights in the general store/mercantile. This is the episode where Hoss buys a bag of candy and ends up giving it to a little boy, and Ben says something about not wanting any of his sons to look like a riverboat gambler. Ben and Hoss leave while Joe and Adam stay in town for Joe to get his haircut.
Next the body of a murdered woman is brought into town by her husband, Flint Johnson. He says 3 men were seen riding away. Adam mentions that it doesn't necessarily mean they were the ones who did it.
Later Deputy Sheriff Jeb Clanton asks Joe and Adam to join the posse that Flint is having put together. The scout will be Paiute Scroggs. Joe and Adam agree to join the posse ~ with reservations of what it may turn into.
The posse leaves to look for the killers ...
