Mrs. Ratcliffe's Revolution (2007)

"She left the land of Marks & Spencer and went to the world of Marx and Lenin."

Based on a true story, Mrs. Ratcliffe's Revolution is the tale of a family from Bingley in Yorkshire, who defect to East Germany. Here they find a nightmare of rationing, censorship and the most spied upon people in history rather than the Marxist utopia they were expecting. But if they thought getting in was difficult wait until they try to get out.
