Robert "Bob" Sands a rowdy cowboy, leads his friends in tearing up an Arizona town that has gone distressingly "dry," until members of the Law-and-Order League hog-tie Bob and ship him East on a passenger train. Bob, out for adventure, goes on to New York and becomes the guardian of the wild-tempered Larry Harrington, a millionaire's son. Larry commissions Bob to deliver love letters to waitress Mary Lee, an entanglement forbidden by Harrington, Sr., but Bob falls in love with the girl himself. Mary decides that she prefers cowboys to millionaires, and Bob and Mary wed and return to the West.
