A true-blue socialist in East Germany (Kathrin Sass), abandoned for the West by her husband years earlier, has a heart attack and slips into a coma, leaving behind two grown children; when she regains consciousness six months later, the Berlin Wall has fallen, a fact her son (Daniel Brühl) tries to conceal from her to prevent a lethal shock to her system. German writer-director Wolfgang Becker creates an intriguing story of a family traumatized by politics, then lets it drift off into an elaborate sitcom-style hoax (ah, the blessings of liberty). When the movie got serious again at the end I wasn’t buying, though the whole endeavor is helped along by an appealing cast (particularly Chulpan Kamatova as the nurse/ingenue). In German with subtitles.
