Black Saturday - DVD

Kubíček, a warehouse keeper, steals two demijohns of alcohol from a disused tanker, unaware that it is methyl alcohol. He'll give one to Rezko, the station clerk, and the other to Valen. In the pub run by Rezek's wife Vera, Rezek treats his cronies Málka and Hatina to cheap alcohol and that evening he fights with Valena over Vera. Valena leaves early in the morning for a friend's wedding, unaware that she is carrying dangerous methyl alcohol. Rezek is found badly injured on the tracks and dies soon afterwards. Investigators suspect Valena of murder. When it is discovered that Rezek died of methyl alcohol poisoning, a search is launched for the dangerous demijohn.
