In an Osaka noodle bar, a powerful businessman meets a grisly end—eviscerated and beheaded. Another influential figure sits entombed in his fortress-like underground bunker, anxiously anticipating a similar fate.
Night after night, a spectral woman stalks his dreams: an unyielding assassin backed by a ruthless yakuza army. Systematically eliminating key figures in Japanese business, she appears to be climbing the power ladder towards her ultimate target.
Yet, the man in the bunker has an ace up his sleeve. He marshals his forces to find the enigmatic Azrael and his son, by any means necessary, to protect his life.
What ensues is a storm of epic proportions. Assassins, gangsters, mercenaries, bodyguards, and vengeful sirens collide in a deadly game where every card dealt is a matter of life and death.
