When a cursed videotape that kills viewers in seven days and a vengeful ghost that claims victims through a shared house of horrors collide, the terror multiplies in this chilling Japanese horror crossover directed by Koji Shiraishi. The film follows a group of strangers, including a determined journalist played by Mizuki Yamamoto and a haunted detective portrayed by Masanobu Ando, who discover that a single location is now plagued by both the infamous Sadako from the Ring series and the relentless Kayako from the Grudge franchise. As the two supernatural forces begin to intertwine, their separate curses merge into an even more inescapable nightmare, forcing the protagonists to race against time to break the deadly cycle before both curses claim them. With a tense atmosphere and mounting dread, this 99-minute horror event pits the characters against not one but two iconic entities of Japanese horror, exploring how fear and death can spread and evolve when ancient curses meet. The ensemble cast, including Tina Tamashiro, Aimi Satsukawa, Misato Tanaka, and Masahiro Komoto, must navigate a web of terror where no escape seems possible, making for a gripping experience that horror fans will find both familiar and refreshingly new.
