Sylvain, a 72-year-old man, learns that he is going to lose his sight just as his daughter is about to give birth to her first child.

In 1963, Esther gives birth to Roland, the youngest of a large family. Roland is born with a club foot that prevents him from standing. Against everyone's advice, she promises her son that he will walk like the others and that he will have a fabulous life. From then on, Esther will do everything in her power to keep this promise. Through decades of trials and miracles of life, this film is the story of a true, funny and moving story, that of an incredible destiny and the greatest love there is: that of a mother for her child.
