Quirt Evans handles Carson

A group of Quaker farmsteads had built a community irrigation dam on one family's property, but that family was then bought out by rancher Frederick Carson, who chose to keep all the water to himself. Notorious gunslinger and bandit Quirt Evans (played by John Wayne), who has befriended the Worth family after they saved his life, decides to fix the problem his way: he rides over to Carson's ranch, tells him to let the water flow, backing it up by simply telling Carson his name and letting his imagination do the rest. He then brings Carson over to meet the Worths to smooth things over more permanently.
