Books, apps, coaching sessions: Today, happiness is everywhere. We might think that there is nothing wrong with this common-sense concern. But it’s actually the opposite of social reality. So what lies behind this contemporary obsession with happiness and the billions of euros generated by its industry? Philosophers, sociologists, economists and psychiatrists including Christophe André, Éva Illouz, Martin Seligman and Julia De Funès, confront their point of view and decipher one of the most captivating and worrying phenomena of this early century.

A transformative experience, this emotional documentary addresses some of the most pressing issues of the 21st century, reflecting on happiness, social connection, daily life, death, and aging, while exploring doubts about the "word of a thousand shades and somewhat perverse" concept of success. This film has the potential to change your life and your perspective on the true meaning of success. An intimate reflection on success, it features María Teresa Paniagua, a joyful and unique octogenarian Zarzuela singer. The documentary offers surprising insights from interviews with notable figures from the worlds of art, science, and intellectual thought, including actress Rossy de Palma, philosophers Fernando Savater and Javier Sádaba, tenor Plácido Domingo, monk Matthieu Ricard, psychiatrist Martin Seligman, Harvard professor Nancy Etcoff, and TED Talk speaker and writer Victor Küppers, among others. This documentary is a balm for the soul.
