Katowice, the night of December 12-13, 1981. Military units occupy strategic points in the city. A group of Zomovniks, smashing union security, drags the chairman of the Company Commission of the NSZZ Solidarity in the Wujek mine out of his apartment. The news quickly spreads to the miners. Initially surprised, they soon react with spontaneous protest. On December 14, a strike breaks out at the plant. The miners demand the lifting of martial law and the release of the chairman. When negotiations fail, the army, ZOMO and militia storm the mine.
