Sonata opens with a diagnosis that turns out to be wrong, and everything the family believed about a silent teenager unravels from there.
What is Sonata about?
Grzegorz grows up carrying an autism diagnosis that has shaped how everyone around him treats him since childhood, closing him off inside a world nobody else seems able to enter. As a teenager, that explanation collapses: what doctors had been calling autism turns out to be a severe, long-untreated hearing impairment, one that has quietly hidden something nobody expected underneath it. Once Grzegorz begins to hear and communicate on new terms, a musical gift he was never given the chance to show comes into view, and the film follows what it costs him, and his family, to catch up to who he actually is after years of being defined by a mistaken label. Set in Poland and based on events drawn from real life, it is as much about the years lost to a wrong diagnosis as it is about the talent that survived them.
About the cast
Michał Sikorski takes on the central role of Grzegorz, with Małgorzata Foremniak and Łukasz Simlat among the family and support figures around him, and Jerzy Stuhr appearing in the ensemble that fills out the film's Polish setting.
Context & significance
Sonata is a Polish drama built around a subject that rarely gets sustained screen treatment: the years a misdiagnosis can cost someone before the real condition, and whatever it has been masking, comes to light. Director Bartosz Blaschke keeps the film grounded in family dynamics rather than clinical detail, tracking how a household reorganizes itself once its understanding of a child is proven wrong. The film has been strongly received since its 2021 release, and it sits alongside other recent Polish dramas that use one family's private struggle to say something broader about care, communication, and how easily a child can be misread for years at a time.
