Buck, Manolito and Billy Blue are sent to Tucson for food, supplies and boots, but are sidetracked instead by women and song.

While John Cannon awaits his trio's return with the goods, Buck promptly enters a poker game with cowhand Kansas and loses the supply money, Manolito courts Pearlita who rolls him for his money, and Billy Blue sets out with little Rag-Tag Tina to buy the fanciest pair of boots in Tucson.

Problems grow when the boys try to help Fergus MacLeish and his wife from being held up, only to lose the guns they need in Tucson.
