Young construction worker Ralf Reider leaves his home village Katzsprung in the Rhön mountains during the "Berlin Initiative". In the capital, he wants to earn enough money in construction to build his own house for his wife and his child. But Ralf is an unconventional character who soon becomes an outsider because of his behaviour.
