Lone Star Ranger (1942)

Lean, mean Texas Ranger Jack Benteen locks horns with a former friend, Cash Bailey, now a ruthless drug kingpin. Though they're on opposite sides of the law, they share a love interest in the sensual Sarita. When a crew of rogue soldiers descends upon the border town for an off-the-books mission, all roads lead to a bloody, to-the-death showdown, as loyalties shift and the lines between good and evil are blurred.

Ten years after the Civil War has ended, the Governor of Texas asks Leander McNelly to form a company of Rangers to help uphold the law along the Mexican border. With a few veterans of the war, most of the recruits are young men who have little or no experience with guns or policing crime.

A cattle-vs.-sheepman feud loses Connie Dickason her fiance, but gains her his ranch, which she determines to run alone in opposition to Frank Ivey, "boss" of the valley, whom her father Ben wanted her to marry. She hires recovering alcoholic Dave Nash as foreman and a crew of Ivey's enemies. Ivey fights back with violence and destruction, but Dave is determined to counter him legally... a feeling not shared by his associates. Connie's boast that, as a woman, she doesn't need guns proves justified, but plenty of gunplay results.

Ross Bodine and Frank Post are cowhands on Walt Buckman's R-Bar-R ranch. Bodine is older and broods a bit about how he will get along when he's too old to cowboy. Post is young and rambunctious and ambitious for a better life than wrangling cows. When one of their fellow cowboys is killed in a corral accident, Post suggests a way into a better life for himself and his friend: robbing a bank. Bodine reluctantly joins in the plan and the two contrive to rob the local bank. They make good their escape initially, but Walt Buckman and his two sons, John and Paul, are incensed at this betrayal by their own trusted employees. John and Paul set out to bring Bodine and Post to justice.

Cole Thornton, a gunfighter for hire, joins forces with an old friend, Sheriff J.P. Harrah. Together with a fighter and a gambler, they help a rancher and his family fight a rival rancher that is trying to steal their water.

Jubal Troop is a cowboy who is found in a weakened condition, without a horse. He is given shelter at Shep Horgan's large ranch, where he quickly makes an enemy in foreman Pinky, a cattleman who accuses Jubal of carrying the smell of sheep.

Having fled to Mexico from the U.S. many years ago for killing his father's murderer, Martin Brady travels to Texas to broker an arms deal for his Mexican boss, strongman Governor Cipriano Castro. Brady breaks a leg and while recuperating in Texas the gun shipment is stolen. Complicating matters further the wife of local army major Colton has designs on him, and the local Texas Ranger captain makes him a generous offer to come back to the states and join his outfit. After killing a man in self-defense, Brady slips back over the border and confronts Castro who is not only unhappy that Brady has lost his gun shipment but is about to join forces with Colton to battle the local raiding Apache Indians.

A frontiersman and his son fight to build a new home in Texas.

Passing through a border town, a man is caught up in a Mexican's murder of a member of the town's most powerful family.

Texas Ranger Dusty Rivers ("Isn't that a contradiction in terms?", another character asks him) travels to Canada in the 1880s in search of Jacques Corbeau, who is wanted for murder. He wanders into the midst of the Riel Rebellion, in which Métis (people of French and Native heritage) and Natives want a separate nation. Dusty falls for nurse April Logan, who is also loved by Mountie Jim Brett. April's brother is involved with Courbeau's daughter Louvette, which leads to trouble during the battles between the rebels and the Mounties. Through it all Dusty is determined to bring Corbeau back to Texas (and April, too, if he can manage it.)
