Frank Fay, as a Mexican named Don Carlos, rides into a small Texas border settlement on the Fourth of July in the early 1880s. He is accompanied by his two inseparable companions, played by Georgie Stone and George Cooper. The day is being celebrated in the style of a Spanish fiesta. Fay challenges a rough Texan, played by Noah Beery, to a duel, only to find himself invited to undertake the dangerous task of capturing a cattle rustler who has been stealing cattle from the Lazy Y Ranch. He accepts the task on the promise of receiving $7000 in gold if he can return both the thief and the stolen cattle within 10 days.
