Yoshioka is a stressed-out cop investigating the murder of Reiko Shibata, a young woman in a vivid red dress. Though she was apparently drowned in a small pool of muddy water, her stomach is found to be full of sea water. The most worrying aspect of the case for Yoshioka is that a button found at the murder scene matches one that's missing from a coat he himself bought. When fingerprints on the body match his, Yoshioka starts thinking he may have been the murderer. More bodies start turning up and the victims have been killed the same way. Yoshioka is soon haunted by the spectre of the woman in red. She emits an unearthly wail and wants something from the detective, leading him to an abandoned sanatorium where Yoshioka must solve the mystery and learn his destiny.
