Arbuckle plays a drifter who has caught a ride hiding in a train's water tank but is thrown off the train after being discovered stealing food from the passengers. He is chased by a group of Indians who intend to kill and eat him. He runs to a town called Mad Dog Gulch where he inadvertently foils a robbery attempt by Wild Bill Hickup (St John) and his gang after which the town sheriff (Keaton) appoints him the new bar tender of the local bar "The Last Chance Saloon".
