Emmet Lang is a very unique type of outlaw. A veteran of the Civil War, he returned home to find his family murdered and the family farm destroyed. Bitter and disillusioned, he wandered the south and west and struck upon an ideal way to make a living: stealing from criminals. Lang and his small band of three outlaws plan the perfect robbery. An Indian Affairs agent is traveling by stagecoach to Denver. In his possession is forty thousand dollars he embezzled from funds destined to help the native tribes in his care. Lang and his gang hold up the stagecoach at a way station and relieve the Indian Agent of the forty thousand. It's the perfect crime until Lang's men betray him.
