In the desolate landscape of a nameless Genpei War-ravaged town, two rival gangs vie for unearthed treasure. The white-clad Genjis, led by the sadistic Yoshitsune, and the red-suit-wearing Heikes, commanded by the deeply vengeful Kiyomori, are at an impasse. The tension is palpable as both factions search for the location of buried gold, willing to spill blood for fortune and supremacy. The uneasy balance of power is disrupted when a mysterious, lone gunman with exceptional skills rides into town.

The enigmatic stranger, after demonstrating his formidable prowess in gunplay, cleverly offers his services to both gangs. However, his loyalty is a ruse, intending to play the two sides against each other for his own secretive ends. As the gangs fall for the gunman's manipulation, the town's few remaining residents watch warily, knowing that a ferocious and potentially cataclysmic showdown is inevitable. Among them is a woman who has her personal reasons for keeping close to the unfolding events and may hold the key to the treasure everyone is desperately seeking.
