Uwe is a grumpy old cynic and an incorrigible bore who seems to hate everyone and everything in the world. He lives alone in his house, following strict rules and principles day in and day out, and looks at other people as if they are only trying to ruin his life. But one November morning, Uwe meets his new neighbours, a lively and talkative family that turns his world upside down. New adventures, funny and sad situations, and unexpected friendships will show that behind the mask of an irritated and angry grumpy man, the real Uwe is hiding a touching and heartbreaking life story...
