Krieg der Töne: The 12 year old Ina struggle to become a great pianist. Success depends on the music competition "Ein Herz für Mozart". Ina is sent by her mother's command to piano lessons. The piano teacher Holger produces in his free time experimental music from sound collages, but can not prevail with his works in the professional music business. Ina takes a liking to the sound collages of Holger and flees from her domineering mother to him.
