From the liner notes

From the legendary director of Ringu and The Ring Two comes this eerie tale of ghostly vengeance. The unwitting victim of a terrible curse, a young man accidentally injures his wife, a jealous teacher who soon dies from her wound. Running away with one of her students, he fails to heed the dead woman's warning that if he remarries, she'll haunt him to the grave. And now for an unfaithful husband, the real terror is about to begin.
