John Carter, Hero of Mars

Wrongfully accused of insubordination by a corrupt superior officer, an earthborn military captain escapes under an assumed alias only to awaken on the arid sands of Mars. Taken captive by fierce four-armed nomadic tribesmen, he earns their respect through brutal arena combat and encounters a defiant royal captive fleeing a tyrannical political union. Joining forces with the desperate maiden, the veteran soldier rallies an alien army to defend her besieged fortress. When ruthless invaders threaten the planet's fragile atmosphere processor, the displaced warrior risks life and limb to preserve their adopted civilization.
