Mickey's going golfing, and Pluto is his caddie. Besides the usual caddie duties, Pluto runs to the ball and points to it. But when the ball lands in a gopher hole, Pluto's got another task: chase the gopher. They eventually chase each other through a number of holes in a knoll where Mickey is trying to putt out, causing the knoll to collapse.
