The Spiral

Mitsuo Ando (Koichi Sato), a young pathologist, wants to know why his friend died. The autopsy gives him nothing he can put a name to. His search leads him to a cursed videotape, the same one that killed his friend's wife and son, and to the spirit of Sadako (Hinako Saeki). George Iida films the investigation as a slow tightening, each clue pulling Ando further toward the thing he is trying to explain.
