Suicide Island

Synopsis

In a story evoking both Lord of the Flies and Battle Royale, a young Japanese man, Sei, is transported to the mysterious, remote Suicide Island after a failed suicide attempt—where he must live the rest of his days or figure out how to die! With society turning its back on many suicidal citizens, the island fills up with haunted, driven characters, often in conflict with each other and sometimes barely holding onto sanity!
