Yoshiaki and his wife, Keiko, are a young couple living an ostensibly quiet and happy life when Yoshiaki is repeatedly seized by inexplicable fits, complete with spasmodic jerks and demonic howls. They call in Sakashita, a pudgy, well-meaning junior of Yoshiaki’s at medical school, but he proves to have different plans for Yoshi and wants to keep him internal to the hospital. When the last one escapes from there, things are getting messy and his transformation to a mutant starts with terrible results to everyone. A good film with some bits of suspense, some other funny scenes and a cliche plot that turns into a crazy story. Expect the unexpected but remember always it is still a Japanese film.
