Jan Hus is a 1954 Czechoslovak film directed by Otakar Vávra. It is the first part of the "Hussite Revolutionary Trilogy", one of the most famous works of the Czechoslovak director, completed with Jan Žižka (1955) and Proti všem (Against All Odds, 1957).
The catastrophically dry weather of 1947 causes immense problems in the countryside. In the small village Klícov, only farmers Hánek and Bervida and the old Hromádka have water. The others must queue every day for a drop for themselves and their cattle. All the villagers lament over their previous decision to turn down the cooperative chairman Kouba's proposal to built a new village water-supply system.
