Knowing that he will soon pass on, elderly Valentin Grack hires private detective Stanislav to follow him around for an entire day and write down everything that he does. It is a cold day and during Grack's travels he encounters a younger woman who addresses him as professor. He then meets a prostitute who turns out to be his daughter, and finally he meets an old woman, his worried wife who has been searching eight days for him. In between meeting the women, Grack finds himself in some almost surreal situations and having flashbacks about his youth.

Герой фильма профессор Грэг — человек — загадка: он нанимает сыщика, который должен следить за ним и записывать его слова и поступки. За этими странностями проступает одиночество человека, не вписавшегося в окружающую его реальность. Это путешествие по дорогам памяти, снов, фантазий.
