Parasite

Sebastian Summerland starts his forty-eight hour shift as normal, says goodbye to his wife and children and expects to see them after two days. Little does he realize is that the city of Numont would be turned into a living nightmare in a matter of hours.
An illness starts to spread like a wildfire, the infected becoming ravenous—attacking and eating any people and animals they can get their hands around.
Outside help isn't coming and Sebastian struggles to keep his family alive and teams up with other survivors, not only to fend themselves against the undead but also the living. If their new reality wasn't frightening enough, the survivors come to a conclusion that something might be coordinating the infected. Even more dreadful, the outbreak might have been purposefully released on Numont.
