As a police officer named Carter passed by on one of the roads, he suddenly discovered that there was a man with blood on his feet as he limped along an abandoned road. The officer began to think and rushed to the local hospital with the help of a staff member to do what was necessary. The officer found that the hospital was surrounded by other similar figures. Everyone, whether sick or employed, has turned into a strange state of activity in order to protect the survivors in a state of great daze. Carter will pull everyone who is inside the hospital into the depths of the hospital to protect them but they will reach that gate, which leads to great evil.
