Great Britain is thrown into turmoil after being struck with a mystery epidemic. One of the first victims of this disease is the Prime Minister's daughter. With a vaccine in development, but far from completion, the Prime Minister decides to speed through the process. A deal is struck with an all girls school in Kent to act as a guinea pig for the vaccine. Every pupil at the school is given this jab which leads to disastrous consequences. The Army seal off the school, creating a quarantine zone with a handful of survivors left inside. What has the Government told the parents? Why have all communications been blocked to the school? Why is a transit Van visiting the School on daily basis? What are those strange noises coming from the School grounds?" And who are the Masks?
