Isolation Ward New Year's Day, Dr. Matsuo (Satoshi Tsumabuki) of a city hospital accepted an emergency patient. The patient had high fever, convulsions, hemoptysis, and severe visceral damage, but the disease could not be diagnosed. Because there was no effective treatment, the patient soon died. Before Matsuo could recover from the depression, the situation had already escalated rapidly. Led by his colleague Dr. Ando (Koji Yakusho), some medical staff were also infected with this strange disease, then it spread to patients and visitors... Countless people in the hospital were infected with the virus, and the whole hospital fell into chaos. The World Health Organization sent Eriko Kobayashi (Rei Dan) to investigate the cause and prevent the infection from spreading. When Matsuo saw Eriko, he was greatly shocked. Originally, they were a couple, but because Eriko went abroad for work, they went their separate ways. Without hesitation, Eriko isolated the entire hospital building and requested that the hospital accommodate new patients, prioritizing treatment. Starring Satoshi Tsumabuki, Rei Dan, Ryoko Kunizaki, and Yuji Tanaka.
