Karel, a young man with an unknown past, but with a defined set of values and an ideal moral code, arrives in the village in the middle of the harvest. For the ordinary, down-to-earth villagers, Karel's lifestyle is hard to understand and they simply do not accept him into their midst. The summer ends and he leaves with his message again somewhere else. Perhaps he will return here next year to try to repeat his strange mission...

It doesn't help to have an exacerbated situation like a family losing their only son - killed in a motorcycle accident. His parents, however, don't know the girl who survived, now being treated at a local hospital.

The Czech film Svítalo All Night was made to commemorate the 35th anniversary of the liberation of Czechoslovakia by the Soviet Army and is dedicated to all those who fought and gave their lives in Prague in the May Uprising of 1945. Behind the historical events, the creators see mainly their simple, unassuming participants. Thus, we are presented with a number of apt portraits, whether it is the central hero Dr. Soukup and nurse Daniela on the side of the fighting Czechs, or a captain and a simple private in a Red Army unit coming to the aid of the fighting Prague, or an old, war-weary German major, who only realises the senselessness of the war at the sight of a fanatical, cynical lieutenant for whom Nazi ideology represents the meaning of life.
