You can't lock up a man's whiskey

Marshall Rooster Cogburn (John Wayne) loses his badge because his kill count is incredibly and worryingly high. He drinks too much as well. And let himself go a little. When some real job - catching nitroglyserine and gun thieves - needs to be done, they recruit him back. Teaming up with Christian missionary Eula Goodnight (Katharine Hepburn) and a Native American Wolf (Richard Romancito), he eats bandits for breakfast.
