Viscera (Antidote)

In the aftermath of a flesh-eating plague that has wiped out most of humanity, a surviving man and woman face unimaginable horrors when he suddenly becomes infected. Confined to the basement of an abandoned farmhouse, she tends to him as his body rapidly deteriorates over the next four days. But they soon find themselves up against more than just the disease. A crazed infected woman begins to stalk the farmhouse. A suspicious stranger arrives promising the key to survival. And the only possible cure is an injected drug that slowly drives you insane.
