Scotland has been hit with a deadly epidemic called the Repovirus. The British government chooses to contain the disease by building a barricade and leaving the people to die. The people are desperate to get out of Scotland and there is mass panic. A young woman pleads with a soldier to take her daughter who was shot in the eye during the chaos. They take the child and leave the mother and all of Scotland to fend for themselves. The child was raised in England and is now a top police officer. Eden Sinclair (Rhona Mitra) uses her high-tech glass eye as a camera to track the bad guys. When the Repo-virus begins to spread in London the government gives Eden forty-eight hours for her and a special task force to go into Scotland. Their mission is to find Dr. Kane (Malcolm McDowell) who had been working on a cure. Once in the city of Glasgow they are attacked by crazed, cannibalistic gang. Their leader Sol (Craig Conway) thinks that Eden is their ticket back into England and lock her up in a dungeon while they ritualistically eat her teammate. Eden is able to escape and takes a fellow prisoner, Cally (MyAnna Buring) who knows where to find Dr. Kane. The team scrambles to escape the clutches of the crazed gang and escape into the hills. In the mountains far away from the city other survivors have retreated to middle ages. The ruler Dr. Kane has created a new empire adopting the ways of the cruel middle ages. Eden her team must defeat both Dr. Kane and his soldiers as well as Sol and his gang before the time is up and London suffers the same fate as Scotland.
