Bonanza - Season 13 Episode 20 : Shanklin 1973

A band of ex-Confederate soldiers demands $25,000 from Ben. When Hoss resists their demands and tries to fight them, their leader, Shanklin, shoots Hoss in the abdomen. Hoss lingers near death, and when the doctor is unable to complete the surgery, a nearly inconsolable Ben persuades Shanklin (a confident, competent doctor) to save his son's life. Meanwhile, Jamie - who had witnessed the shooting and nearly got shot himself - searches high and low for Joe, who is involved with a beautiful starlet and intently focused on a poker match.
