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.
