The story takes place in the second half of the eighties. The regime of power is tired, but any changes are out of sight. Some people are trying to find their asylum in their privacy, some defect. Who is not willing to get adapted, lives at the outskirts of the society. So, for example, the forty-year old intellectual Ewald (György Cserhalmi)can not perform his profession, as he could not comply with requirements of the political regime. He earns his living just to sustain, and at the moment he is assigned to measure the capacity of water bore in the vicinity of the fortress. He lives in a caravan-trailer, measures the yield of the water source, and makes friends with the head officer of the fortress (Miroslav Donutil). Their friendship is a strange, unusual relation of two men of different characters, linked by a feeling of loneliness, need of sincerity and even a mutual respect, which stems from understanding each other.
