Memory Lane is the story of an elderly Italian film director commissioned by a French producer to make a film about the life of Proust. During the preliminary preparations, which take him back and forth between France and Italy, Proust's great description of involuntary memory becomes real for him as he starts to relive key moments from his own past. In a series of free associations (visual, tactile, acoustic) he experiences breaking with a group of partisans fighting the German occupation, falling repeatedly in love with the same woman whom he fails to recognize after a long separation, taking her to Switzerland for an abortion, and his relationship with his 20-year-old son who mirrors back to him his own youth.
