Scenes from the life of composer Zdeněk Fibich accompanied by excerpts from his work in a poetic documentary... The story of the Czech artist is embodied in a single day in the life of his collaborator and lover Anežka Schulzová (Iveta Rálková). Between waking up in the morning and falling asleep at night, she brings fragments of her beloved man's life experiences to life in her memories. It is a drama of emotions that draws her into its trap. Fibich left the safe haven of his family for her love, seeking inspiration in passion and eroticism. This clearly tense human situation is complicated by Anežka's rival and Fibich's wife Betty.
