It is June 1694, and Reiko, the beautiful wife of Sano Ichiro; Reiko's friend, Midori; the shogun's mother; and Lady Yanagisawa, wife of the shogun's powerful second-in-command, are kidnapped en route to Mount Fuji and imprisoned in the tower of a ruined palace. The shogun demands quick action – and under the threat of death, Sano is forced to work with his sworn enemies, Yangisawa and Hoshina. The women are in imminent danger and the delivery of a ransom note only complicates the situation – revealing a surprising target for the kidnapper's plot, and creating another impossible situation for Sano.
