A series of horrific murders have just gone viral, posted anonymously by the handsome and seductive Nomura (Kazuki Kitamura) with a taste for torture. Thousands of miles away, disgraced journalist Bayu (Oka Antara) can't stop watching and in a reckless moment discovers he, too, can kill. One man in Tokyo. One in Jakarta. A serial killer and a vigilante. As the posts multiply and the body count rises, a bizarre and psychotic rivalry begins and the face-to-face showdown that's coming will paint the city in blood.
