Dürrenmatt – A Love Story is a cinematic monument to the man, thinker, writer and painter Friedrich Dürrenmatt. The film focuses on the love story between Friedrich Dürrenmatt and his wife Lotti Dürrenmatt-Geissler. For 40 years, the two lived shared a very close relationship: there was no work he did not discuss with her, no rehearsal to which she did not accompany him. In later years, their relationship became increasingly tense. After Lotti's death in 1983, Dürrenmatt plunged into a deep crisis from which he tried to free himself through a new love.
