Plot Summary

A documentary crew follows the December 1978 “big repair” at the Bernburg (Saale) cement works, normally shut only for maintenance, where management has cut the planned 16-day turnaround to 14, with a 15 000 M bonus (rising to 20 000 M if finished a day early). As cameras roll through cement dust, crew and workers discuss the twice-yearly overhaul, familiar crews, and gritty camaraderie. They learn that chronic spare-parts shortages force constant improvisation, and that bureaucratic red tape weighs heavier than the hardest labor. Amid pride in their long-running plant, workers confess simple hopes for health, peace, and family. By film’s end, the crew realizes the true “core” of the factory lies not in its machinery, but in its people’s hands and minds.
