It is 1989 and Alex (Daniel Bruhl) and his sister Ariane (Maria Simon) live in East Germany with their mother, Christiane (Katrin Sass). When Christiane wakes up, doctors warn Alex that any shock could bring on a fatal heart attack, so he decides to convince his mother that her beloved Communism has not been overthrown, but is in fact triumphing over Capitalism; and Alex sets about recreating every detail of the old East Berlin in their flat.
