On the worst day of his life, a man seeking honour, and a reason to live, confronts death. Mugen, a Japanese immigrant living in Auckland, awakes to news of his grandfather’s death. Mugen suffers from a history of mental illness and the bad news hits him hard, leading him to contemplate suicide, and causing him to have hallucinatory visions of a Dark Samurai who has been plaguing his nightmares and stalking him at every turn. In the midst of his mental breakdown, he makes a new friend and a few new enemies. Mugen’s strong desire to live up to his samurai heritage and make his grandfather proud leads him to a final confrontation with death, at great risk to himself, in the name of honour.
