Romain Valincki is 15 years old. He understands this only thanks to the passport, in which he does not recognize himself — after the accident, the boy was diagnosed with amnesia. On the advice of a doctor, Romain begins to keep a diary, which he trusts with all his secrets, and goes in search of himself and the broken threads of the past.He has to look at his life from the outside. The father — domineering and uncompromising — suspects his son of lying and manipulation, as soon as the boy is discharged from the hospital. The mother, stern and laconic, does not see a problem in violating personal boundaries. And Romain still needs to go back to school, where he is not able to distinguish friends from enemies. Everyone in this story can help him remember and understand what happened, but also any of them can impose on him their version of not only the past, but also the present.
