The young scientist Dr. Květ devotes all his interest to his successful scientific work until the moment he falls in love with beautiful Evelina. Evelina reciprocates his feelings but when she realises that his scientific work will always be an obstacle between them she separates from him. She then marries Václav, a forester. With her husband, child and an eccentric father-in-law she lives happily in a forest cottage. Five years later she happens to meet Dr. Květ who is has hardly any strength left in him. Evelina has to choose between the love of her family and the love and sympathy she feels for Dr. Květ. She decides to help Dr. Květ, but her sacrifice is futile. The exhausted scientist commits suicide. Evelina, like a repentant Magdalene, returns to the forest cottage. Her husband has shot himself in desperation, her child is very ill and her father-in-law is bent on revenge. At an opportune moment an old scientist appears, Dr. Květ's, father who manages to reconcile Evelina and her father-in-law. Peace returns to the forest cottage once more. (According to an article appearing in the press at the time the film was made.)
The film was shot with Russian actors, emigrés who left soon afterwards for Paris. Theodor Pištěk took over Šuvalov´s role and shot the missing scenes. Jan S. Kolár completed the film which director Boris Orlický left unfinished.
