Grzegorz Płonka spent years in complete silence, having been diagnosed with autism. Thanks to the tenacity of his parents, the support of an educator who does not want to bow down to a diagnosis she considers incorrect, and implant surgery at the Institute of Professor Henryk Skarżyński, he regains his hearing. He can thus realise his greatest dream: playing Beethoven's 'Moonlight Serenade' on the piano. From a true story, the story of overcoming barriers that seemed insurmountable.
