At a family dinner, Iris learned from her 74-year-old father Jean that he wanted to be 75 for his last birthday. The absurd news was like a heavy blow. Iris didn't see it coming at all. As her father's birthday approached and Iris was about to collapse, she decided to jump out of the script. She asked for leave, moved in with her father without permission, and tried to force him to answer a question that was important to her: why? There seemed to be no satisfactory answer, so she decided to find a way to deal with her father's last wish.
