A woman of about fifty, Martine, and a ten-year old girl are taking a walk together. They are talking; Laura, the little girl, wants to know what Martine is currently doing - Martine is making a film.

Martine tells her her lifestory, she explains about her disease, explains how she was invited to talk about it on April 5th, 2003, when a special conference was held in Amiens to celebrate the 500th kidney transplant done at Amiens's teaching hospital (CHU).
