This is an excellent movie that speaks about Germany before and after the wall. A boy tries to protect his mother from a second heart attack which might kill her, by removing the stress from her life. How does he do this- By keeping her in an enclosed world and controlling the info she has access too. He does this in the same way the old German government had, which he was opposed to – ironic.
As the movie progresses he goes to greater and greater lengths to keep the secret from his mother, prompting funnier solutions and lies. It's both heartwarming and hilarious.
It's an excellent film with a good background into Germany around the fall of the wall, and a must see.
