Paris, autumn 2015. In Philippe Dayan's analysis office, a surgeon in disarray in love, a couple in crisis, a suicidal teenager follow one another day after day. On a November evening, killers enter Paris.
The life of Philippe Dayan five years after the Bataclan attacks, after the first confinement in 2020. The psychoanalyst puts his therapeutic processes to the test with four new patients: Ines, a solitary lawyer with a tidy life, Robin, young overweight teenager victim of school bullying, Lydia, a student who came to share dark news about her state of health and Alain, a business manager in media turmoil... Divorced, sued by the family of one of his former patients, Dr. Dayan turns to Claire, a high-profile analyst and essayist whose support he hopes for the ongoing trial.
