The world-renowned pianists Martha Argerich and Stephen Kovacevich, two giants of classical music, are seen here under the scrutiny of their daughter Stephanie, now in her thirties and a mother herself. 'Argerich' is a warm, intimate and often funny family portrait filmed over 2 decades and around the world that questions the relationship between a mother who is a quasi "goddess", and also a very private person, and her three daughters. Stephanie also uses the film to try to reconnect with her somewhat estranged father. 'Argerich' explores with great subtlety the joys and difficulties of combining motherhood with an artistic career. A remarkable journey into the Argerich galaxy, with all its eccentricities, idiosyncrasies, problems, and, most importantly, love of music.
