Telma (actress Alexandra Lamy), a single mother of a 12-year-old teenager, is not complaining about her life. Of course, she works hard and is always busy. So much so that one morning, while walking her son Luis to school, she looks down at her phone and doesn't notice the child jumping out into the street, where a car is speeding down the road.  In the hospital, after learning that Luis has fallen into a coma, Telma would do anything to turn back time. Unfortunately, she has to face a new reality full of guilt. One day, under her son's pillow, she finds a notebook in Luis' childish handwriting with ten things he would like to do if the world were in imminent danger of destruction.  Telma is gradually obsessed by the nagging thought that, in order to get her son back, she has to make the wishes on the list come true. Once she has experienced what Luis has dreamed of, she will be able to tell him her experiences, which will make him realise how wonderful this world is and make him want to come back. Of course, a 12-year-old's dreams being realised by a 40-year-old inevitably seem unexpected and sometimes ridiculous, but Telma doesn't care. On a journey of discovery and wonder, from France to Portugal to Japan, Telma rediscovers the joy of life and feels an inner connection not only with her son, but also with herself.
