Set after the American Civil War in the 1870s, 'Texas Rangers' is a story about a group of men determined to maintain peace and contain the chaos that is erupting on the Texan frontier. Native Americans are attempting to reclaim their land, Mexicans are pouring over the U.S. border, and renegade outlaws are tearing up the state, so the Texas Rangers swear to protect the innocent and their loved. To do so, they must be willing to maintain the peace where law enforcement cannot, fight while they are out-manned and out-armed by the opponent, and be willing to die for the freedom for which they fight.

Blondie (The Good) is a professional gunslinger who is out trying to earn a few dollars. Angel Eyes (The Bad) is a hit man who always commits to a task and sees it through, as long as he is paid to do so. And Tuco (The Ugly) is a wanted outlaw trying to take care of his own hide. Tuco and Blondie share a partnership together making money off Tuco's bounty, but when Blondie unties the partnership, Tuco tries to hunt down Blondie. When Blondie and Tuco comes across a horse carriage loaded with dead bodies, they soon learn from the only survivor (Bill Carson) that he and a few other men have buried a stash of gold in a cemetery. Unfortunately Carson dies and Tuco only finds out the name of the cemetery, while Blondie finds out the name on the grave. Now the two must keep each other alive in order to find the gold. Angel Eyes (who had been looking for Bill Carson) discovers that Tuco and Blondie meet with Carson and knows they know the location of the gold...
