There is something awful going on in the town of New Sanford.

The people who live there are coming down with a strange illness known only as virus F-7. Dr. David Carter comes to town for his uncle's funeral and meets up with Rachel James, the medical transcriptionist who worked at the New Sanford Clinic with his late uncle.

Dr. David Carter replaces his late uncle at the clinic and together they investigate Vorchang Pharmaceutical Company, the new owner of the clinic, to discover why anyone who inquires about virus F-7 either ends up dead or missing.
