South of the Rio Grande

After several years' dormancy, the "Cisco Kid" western-film series returned to the screen with Monogram's The Cisco Kid Returns. Duncan Renaldo, actually Rumanian, starred as the Mexican "Robin Hood of the Old West", with Martin Garralaga as his corpulent sidekick Pancho. In the tradition of 20th Century-Fox's earlier "Cisco" efforts, our hero comes to the aid of an orphaned child, clears himself of a kidnapping charge, and proves that a "solid citizen" is in fact a criminal mastermind.

Gallant Cisco "kidnaps" murder suspect Ellen from the authorities, then sets about to prove her innocence, all with the cooperation of a sympathetic sheriff.

The Cisco Kid and Pancho are mistakenly identified as leaders of an outlaw band. While the cavalry runs them down, they must hunt down the real bad guys.

Cisco and Gordito arrive to find there is an outlaw operating in the area who is assumed to be the Cisco Kid. When a reward is offered for his capture and a large shipment of money goes out, Cisco is on hand. Seeing the gang rob the stage he goes after them only to be wounded. The gang leader leaves Cisco's handkerchief at the scene and now he is wanted for the murder he tried to break up.

When old rancher Cordoba's grandson is murdered, the Cisco Kid takes his place to find who's trying to take over the ranch.

Cisco and Pancho set out to clear their names in a series of stage robberies committed by two thugs who are impersonating them.

In Old California, a young Frenchman transporting a chest full of silver travels by stagecoach to San Marino, to complete a complex business deal. The stagecoach is ambushed by a band of men whose leader, a mysterious bandido known as Cisco (Gilbert Roland), claims the silver is money that was extorted over a period of years from the poor people of California. The bandits take the money and escape, but Cisco stays behind with the Frenchman - who, it turns out, is actually a lovely mademoiselle, Jeanne DuBois (Ramsay Ames). She follows him to the bandit's lair, where Cisco tells her he intends to return the stolen money to the poor people. The two rivals are irresistibly drawn to each other, however, and as a token of love Cisco offers to return the money to Jeanne instead. Now she must decide whether to complete her business deal, or to comply with Cisco's wishes and redistribute the wealth.

The Cisco Kid (Gilbert Roland) sets out on a double mission of rescuing a girl from forsaking her true love by marrying a supposedly wealthy suitor to save the old family hacienda, and he is also after the outlaws that robbed a stage carrying gold for the Mission. His task is made easier once he learns that the "wealthy" suitor (Tristram Coffin) is also the man behind the gold robbers.

The Cisco Kid (Gilbert Roland) hears of a land-swindling scheme devised by the police Commandante (Martin Garralaga) and the tax collector (Harry Woods) in a small western town. Cisco's efforts against the plot cause the thieves to fall out, and Cisco is able to return the land to the rightful owners.

Chasing women and staying one step ahead of the law, the Cisco Kid meets Raquel and then Dolores. He sees that Raole is the boy friend of Raquel but engaged to Dolores. Learning that all her money will got to her uncle Don Jose when she marries Raole, Cisco suspects a plot and sets out to unravel it.

Eduardo Belmonte overhears his new step-mother, Maria, and her lover, Don Ricardo Gonzales plotting to take over the Belmonte rancho on the night of the fiesta given by her husband, Don Carlos Belmonte. Eduardo offers Maria money if she will depart the hacienda premises, but she refuses and then accuses Eduardo of making love to her. The old Don doesn't take kindly to his son hitting on his step-mother and attacks him in a rage. The lights go out, the father is killed and Maria blames Eduardo, who escapes from the house, chased by Ricardo's men. The Cisco Kid and Pancho rescue Eduardo, who has been shot, and hide him while they investigate. Cisco discovers that bullets from Maria's gun, a handy little derringer, are the same type that killed Don Carlos. But the Alcalde arrests Cisco and Pancho, and Cisco is "supposedly" executed by a firing squad, but IS NOT shot and escapes by a trick. And now Maria and Ricardo are in real trouble with Cisco on the loose.
