Oscar and his sister Linda are recent arrivals in Tokyo. Oscar’s a small time drug dealer, and Linda works as a nightclub stripper. One night, Oscar is caught up in a police bust and shot. As he lies dying, his spirit, faithful to the promise he made his sister that he would never abandon her refuses to abandon the world of the living. It wanders through the city, his visions growing evermore distorted, evermore nightmarish. Past, present and future merge in a hallucinatory maelstrom.
