Charlotte is married with one son and is a doctor in a clinic in Brussels. She has sex with patients in an apartment, selecting the men as if setting up a scientific experiment: They are all unusual, very hirsute, coarse, fat or old. The marriage teeters when her husband Max finds out. Charlotte starts therapy to discover what is going on with her, but her confused desires cannot be described in words. In the end, the family moves to India, where Max has a job as an architect. Charlotte gives birth to twins.

Leopold has her characters perform in rooms that have been carefully arranged and precisely lit. Containers for whirring particles.
