Kiyoshi Kurosawa’s (Cloud, Chime) first samurai film begins when Lord Murashige Araki (Masahiro Motoki) rises up against the tyrannical Nobunaga Oda (Bando Shingo), finding himself besieged within the walls of his own castle. Isolated, Araki is confronted with a series of mysterious crimes that shatter the fragile order of his court, plunging the fortress into fear and suspicion. With Oda’s army closing in and a traitor hiding among his ranks, Murashige is forced into an uneasy alliance with a brilliant yet dangerous strategist (Masaki Suda), who’s being held prisoner in the castle dungeon.
