Infection

is a 2004 Japanese horror film directed by Masayuki Ochiai. The film is about a run-down hospital where a doctor's mistake unwittingly creates horrific consequences for the staff at the hospital. The film was adapted from Ochiai's earlier screenplay from Tales of the Unusual. On its release, the film was part of the six-volume J-Horror Theater series. On the film's release in Japan, it was the second highest gross film at the weekend box office, only being beaten by the film I Robot. Plot At a run-down, understaffed hospital, Dr. Akiba refuses to admit a patient with a strange black rash and is alerted to a serious crisis in Room 3 where a burnt victim dies, having apparently been given the wrong drug. Akiba, Dr. Uozumi, and four nurses decide to cover up the cause of death and move the body to an unused room. The head nurse then discovers that the patient that Akiba previously refused to admit has been left in the hallway and informs him. However, when Akiba goes to check, he discovers that Doctor Akai had taken the patient and decides to study his symptoms: though he is still alive, his body mass is liquefying into green goo. Not knowing how much Akai knows about the events in Room 3, Akiba and the others reluctantly agree to help with the examination but when they return to the patient's room, they find he has vanished and the head nurse unconscious.
