On his first day, the local bank is robbed by the nefarious outlaw William "One-Arm Bill" Johnstone. John vows to the residents of Sundown City he will bring One-Arm Bill to justice, and he sets out on a quest to find and capture the elusive criminal. Along the way, he meets and falls in love with a beautiful, young woman named Snow Rose, a member of a small Native American tribe with a village not too far from Sundown City. But everything changes overnight when One-Arm Bill learns of John's affection for Snow Rose, kidnaps her, and flees into the surrounding countryside. Will John be able to find and rescue Snow Rose, or will his one true love be lost forever?
