P.A.M.

Shelia awakes to find her city's residents has turned into flesh eating, sexually charged, zombie like creatures. She is attacked and quickly rushed off into a military hospital. Inside the hospital she realizes that her nightmare has just begun when the infected begin to turn. She reluctantly befriends a soldier to escape the hospital, but he is badly bitten. He manages to get her to the ammo room where they learn of a cure that can end the mayhem. They meet up with John and Dean, two friends that survived the chaos outside in the city, who are also in desperate need of a cure. Together they fight through the horde of the infected in search of the one thing that could save their city and maybe the world.
