Tři tuny prachu

The Prague Research Institute of Air Engineering is to prepare a proposal to reduce dust in Ostrava, especially in the area where the new power plant is to be built. That is why engineers Vojtěch Spára and Jiří Zástěra will travel to Ostrava. Eva Frágnerová, a hygienist, will strongly oppose the power plant project near the housing estate.
