In a time when demons and ghosts threaten to bring total devastation to a powerful kingdom, betrayal from within the powerful ranks of the ruling emperor threatens to bring an entire civilization to its knees in this supernaturally charged martial arts epic from director Yojiro Takita. As dark forces hold a suffocating grip on a once powerful kingdom during the Heian period, the emperor employs the help of the Onmyoji in keeping the malevolent spirits at bay. Though the coming birth of the emperor's heir offers a glimmer of hope for the kingdom's future, an intimate betrayal leaves the fate of the kingdom in the hands of Seimei (Mansai Nomura) -- the most powerful of the Onmyoji. As Seimei prepares to do battle with his former master Doson (Hiroyuki Sanada), the powers of lightness and dark come together for a battle that will determine the fate for generations to come.
