Prospective hotel owner Carlos is having problems with the completion of his hotel on the Adriatic. He quickly asks his niece Vivi in Germany to cancel the bookings he has made so far. Unfortunately, his telegram reaches her too late and a motley group of guests arrives. They promptly pitch tents in the garden of the half-finished building.
