András and his daughter Zsófia enjoy a relaxed Sunday in their stately city mansion, just before the collapse of the Austro-Hungarian monarchy. But soon the silence in the house is disturbed by an escaped pig, closely followed by an unexpected visit: András’ brother, his large family and lots of luggage barge in through the front door. Running children and garrulous relatives bring noise and bedlam to all floors. Art objects are handled without permission, furniture is moved, objects fall to the ground. The visitors have brought chaos. Zsófia’s father and the maid try in vain to restore calm and order. Though András and his brother get closer to each other, the old house is not up to the changed circumstances. A leaking water pipe heralds a finale that at least makes them all stand still together.
