Sadako 3D (貞子3D) is a 2012 supernatural horror film directed by Tsutomu Hanabusa, loosely based on the novel S by Koji Suzuki.
Thirteen years after the original film, two suicides prompt Detective Koiso and his partner to investigate a string of mysterious deaths.
While Koiso is unconvinced, his partner deduces that the deaths are the result of a cursed video that online artist Seiji Kashiwada created.
Meanwhile, Koiso and his partner scout Kashiwada's apartment, noting the furniture and decorative wallpaper, which look like a set.
Akane is a telekinetic who displayed her power years ago when a maniac attacked her high school.
Until his partner commits suicide in front of him, Detective Koiso continues to doubt the existence of the film, even when it is revealed that the original broadcast of the online video killed its initial viewers and employees of the site where it was uploaded.
A legion of imperfect Sadakos arrive, but her fear triggers her telekinetic powers, which decimates them.
The roof gives and Akane drops to the floor below covered in Sadako's hair, but she escapes alive.
In a mid-credits scene, it was shown that just outside the building beside the well, Kashiwada's landlord moves away and her words, "Isn't it all artificial?"
