The Lone Ranger

In 1865, Captain Mark Smith of the Confederate Army leads a band of deserters to conquer Texas and rule it as a dictator. In one their first actions, they ambush and apparently wipe out a contingent of Texas Rangers, although they leave one injured survivor. The survivor, nursed back to health by Tonto, swears to avenge the massacre and defeat Captain Smith (who has assumed the identity of Texas' new Finance Commissioner, Colonel Marcus Jeffries, after having the real man murdered).
