Basement Dwellers — Holly Copella

A viral outbreak at a hospital leaves a mortician, sheriff, and coroner fighting for their lives against a horde of undead and the CDC. After a massive car wreck leaves several survivors in critical condition at the local hospital, a surgeon uses experimental drugs on his critical patients and accidentally causes a zombie outbreak. When local mortician, Lexx, receives an infected corpse as her client, she becomes stranded in the hospital basement during CDC quarantine along with the local sheriff and the coroner. The infamous surgeon struggles to find a cure for his infectious blunder by using the other survivors as test subjects. Meanwhile, Lexx and the sheriff attempt to locate his missing sister, who's stranded somewhere in the battle zone that once was the emergency room. It's a race against time and the ravenous undead. Can they survive the undead before CDC sanitizes the hospital of all infection?
