Rainer toils by the sweat of his brow on a building site. His first job as site manager is his much-needed big break. Rising rents in the city have already forced him, his pregnant wife and 13-year-old daughter Doreen to move into a little house in the outskirts which needs renovating. At first, Doreen is not thrilled about her new life but then she meets her neighbour Mara, a girl whose parents are as rich as they are narrow-minded. Before long the new friends are playing with fire. Mara incites Doreen to play some nasty tricks and also entangles her in a theft.
