A glimpse of the routine of the pianist couple Martha Argerich and Stephen Kovacevich, two giants of classical music, as seen through the eyes of their youngest daughter Stéphanie. An intimate family portrait that questions the relationship between queen mother and her three daughters. How to reconcile motherhood and an artistic career, personal fulfilment and marital? This tender documentary invites the viewer to experience the intimacy of their home life without any restriction. It is a deep immersion into the Argerich galaxy, a somewhat unusual feminine and matriarchal family.
