 In this Hoot Gibson version/swipe of the "Zorro" story,sneaky Lafe Kildare(Hooper Atchley),the crooked cashier of a Texas bank, murders the bank president, Jim Fremont(Edward Hearn), to keep from being exposed as a thief.He covers up his crime, becomes president of the bank and is the leader of a small army of gunmen oppressing the ranchers of Comanche County. Curt Fremont(Hoot Gibson)rides in to investiagte his brother s murder, and convinces Kildare that he is a harmless, brainless, worthless, no-account lazy drifter---and might even be a sissy or a fop---so Kildare decides he isn t worth the trouble of having him killed.Curt s pose also does nothing to impress rancher s daughter Mary Lou Moran(Sally Eilers)as day-by-day he does nothing but lay around and eat and sleep and ignore Mary Lou, and Mary Lou is not use to being ignored.But...night after night,Curt rides out in a Mexican costume as a bandit called "El Capitan" and harasses Kildare s business enterprises to the point of becoming a nuisance.Kildare offers a reward for the capture of "El Capitan." Curt, as "El Capitan" captures himself, robs Kildare of the reward money and turns it over Senora Conares(Mme. Eva Grippon), a Mexican woman whom Kildare has reduced to poverty.While Kildare and his henchies are out of town on a mission to attach the cattle belonging to Mary Lou s father(Robert Homans),Curt has all the citizens busily firing at a shack where "El Capitan" is supposedly hiding, while he saunters over to the bank and steals the account books, which prove that Kildare is a crook. He captures Kildare s accomplice, Tom Vache(Jack Byron),in the murder of his brother, forces a confession from him and takes him to Sheriff Jim Burke(Edward Peil), to whom Curt has already turned over the bank s books.Kildare, in an escape attempt, is thrown from his horse and almost falls over a cliff, but Curt ropes him and turns him over to the sheriff. Along the way, George Mendoza plays "La Paloma" on a guitar just to reinforce the "Zorro" theme.
