Four students died at one time in one place. Asakava Kazuoki is a journalist. His cousin was one of these students. He began his investigation and during it he presumed a new virus. That's why Asakava supposed that the students had been infected at the same time in the same place. Quite fast, this place was found. It was the hotel 'Pacific Land'. He decided to stay there for one night. But when he came there he started panicking. The thought about the deaths in that place was very scared. He feared that he could die too. In spite of that fact, the journalist overpowered his dread. Because the students noted in the registration book, Kazuoki could guess that the guys had watched a videotape. He found it at the hotel reception and began to watch it. At first he saw the dark. And then....A bright spot flushed on the screen as if someone pierced this screen from the back side. The blinking spot gradually began to increase. ..Something sticky and red splashed from the sides. Then there was a picture and the character of the word 'mountain'... An old woman was sitting and looking at the camera. She said something in a strange language. Then, a baby appeared. He was crying. There were many faces, they shouted : "Liar! Swindler!". ..A man's face...And then on the black background, a sign was beginning: " Everyone who watches these frames will die after watching one week later. Minute in minute. If you want to stay alive, you have to do what I'll say. You must...". Instead of explanations, there was an advertisement for mosquito remedy. Asakava had to find the answer, if he wanted to stay alive.
