Pepek and his wife Sima make their living by casting posthumous masks. One day, Pepek decides to make a mask of his friend Lojza alive. Lojza cannot even move during the casting to make the plaster harden properly. As they wait, Pepek's memories begin to pop up in his mind - how he met Sima, a circus rider, who broke her leg and lost her work in the circus, and how they then began to live together.
