The year is 1970. A young girl called Sarah is walking along the boundary of a disused naval base in St. Oswald beyond a sign which clearly says "Ministry of Defence. Keep Out" She stops...
Liz and Simon make their way back to the window, through which Simon climbed in, when he first arrived at R1, but it is now locked. Simon pushes Liz into the room he had originally hid in and closes the door on her. Liz is shocked to see the mannequin that looks like her. Simon goes to look for a way out. At that moment an alarm is sounded.
Simon Randall and Liz Skinner discover the existence of a strange anomaly, known as the “Time Barrier”, that enables them to travel in time to different historical periods in alternate pasts and futures.
