A telegram sends five people on a vacation they will never forget. Arriving at their destination, they decide to spend the night in a mysterious, old mansion during a raging thunderstorm. Little do they realize that a mysterious stranger is about to enter their lives. He tells them about a strange virus that has overtaken the occupants of the town and top-secret experiments that were conducted away from the prying eyes of the world. For the next four days, the small group tries their best to keep themselves alive. They not only uncover the secret that surrounds the old mansion, but they also discover a plot that is so diabolical that it could see extra-terrestrials destroy the world and everyone living on it. Join the small group as they work against time to expose the truth about the government and military leaders, before the government hides their secrets again forever from the prying eyes of the world.
