In London, eccentric piano instructor Madame Sousatzka takes on a new prize protégé, Manek, a teenage Bengali immigrant who displays incredible talent. Manek forms a close bond with his teacher, but soon discovers that she expects her pupils to become disciplined in all areas of life, and not just behind the piano. As he struggles to meet the challenges, Manek must also deal with his mother, who vies with his teacher for his attention.
