You get lost in a dark forest on your way to your ill grandmother's house, and next thing you know, you end up being chased down by hungry wolves. You fall unconscious in front of an abandoned hospital, and are woken up by an infectious disease doctor, who claims that you entered the epicenter of a mysterious, new virus epidemic and that you contracted the deadly viral disease.
He argues that you won't be able to leave the hospital until you're cured from the disease, but assures you that he'll do his best to cure you. As you spend time with him, you come to the realization that he is much more interested in controlling you than nursing you back to health. You also can't shake the feeling that he is hiding something.
