Misty was a revolutionary concept by 2000 AD's creator Pat Mills in 1978 and left its mark on a whole generation of young women. The two identical tower blocks, known as 'The Sentinels' to the locals, stand tall over the town of Birdwood, but only one is occupied while the other remains mysteriously empty. When Jan Richards' family lose their home they decide to hide out in the abandoned block so they can stay together, only to be sent into a parallel world where the Nazis conquered Britain in 1940.
