Boom Town: Farmers and their families, engineers, technicians, criminals and prostitutes were acquired on the construction of industrial facilities in Zenica. Siba tries to help them, working with dedication and love that goes beyond his duty. It is difficult to satisfy everyone and achieve more in this scorching city and Siba makes mistakes, carried by desire to achieve the impossible. With great effort, the builders manage to overcome the maelstrom after the dam burst, and while the first iron runs from the new furnace, Siba, dismissed because of errors committed, leaves a boom town of Zenica.
