In a shadowy and dangerous city, a solitary hitman of Japanese descent lives by the code of bushido, the philosophy of the samurai. His daily life unfolds between relentless missions and caring for his loyal canine companion. This man, who calls himself Ghost Dog, is guided by the wisdom of an ancient samurai text and strives to act as honorably as possible in a world that does not understand him.
Everything changes when a mission nearly costs him his life, triggering a series of events that threaten both his life and his moral code. These loyalties are put to the test when the leader of the criminal organization he works for decides he no longer needs him. In a deadly game of betrayal and revenge, Ghost Dog must confront not only the enemies that pursue him but also the ghosts of a past that haunts him.
As the story progresses, the fusion of cultures and the exploration of identity become central themes. Ghost Dog finds unexpected connections with a young cashier who shares his love for books and samurai culture, all while shaping his destiny with each decision he makes. With a unique visual style and a reflective pace, the film depicts the struggle between following the path of honor and succumbing to the instincts of survival in a world that leaves no room for compassion.
