The Book of the Dead

Overview

When a young noblewoman, Iratsume, falls into a trance after copying Buddhist sutras and walks to a remote temple that women are forbidden to enter, she stirs up the ghost of the executed Prince Otsu. Otsu's ghost then mistakes Iratsume for one of her ancestors, a young woman who came to watch his execution. The beautiful face of this young woman was the last thing the Prince saw before he died, and his ghost cannot rest while her face haunts his sleep.
