WUNDERKINDER tells a tale of three exceptionally musically talented children, who develop a deep and genuine friendship, extending beyond their different religions and nationalities. The two Jewish children Larissa and Abrascha are both virtuosos - one on the piano and the other on the violin. Hanna, a young German girl, is also extremely gifted. Living in Poltava/Ukraine in 1941, they all share one great love: music. Their world is one of curiosity, joy and talent. But when the Nazis invade the Soviet Union, they and their families face mortal peril. Due to the insanity of grown-ups at home and abroad, their world is turned upside down, and they are suddenly no longer allowed to be friends.
