In early 1960s Japan, the life of an ordinary man is completely transformed when, after a violent encounter at a train station, he starts to experience a profound change in his identity. After the fight, he realizes that his memories have faded, and his sense of self becomes a mystery. As he seeks answers, he finds himself trapped in a labyrinth of deception and moral dilemmas that lead him to question his own humanity.
As he navigates the disconcerting urban landscape, he encounters equally enigmatic characters that reflect his own internal struggles: a woman lost in the search for her past, a friend hiding dark secrets, and a detective obsessed with the truth. All of these encounters push him to the brink of madness, as the boundaries between reality and fiction blur.
With stunning visual aesthetics and a non-linear narrative, the film explores themes of identity, memory, and alienation in contemporary society. The protagonist is forced to confront his deepest fears while discovering who he really is. The tension mounts as the mystery intensifies, culminating in an unexpected climax that challenges the viewer's perceptions. This masterpiece of Japanese cinema is both a captivating psychological thriller and a profound reflection on the nature of identity.
