The story happened in a small town in southern Germany. A girl named Lala was raised by deaf parents. There has been a little game of guessing sounds between Lala and her parents, such as the sound of sunrise and the sound of snow. The only time that lesbians can communicate with people normally is when they are in school. With the silent care of her parents, Lala grew up. She was the only person in the family who could listen and speak. She was a bridge between her parents and the outside world from childhood until she began to learn clarinet. At a Christmas family gathering, she met her aunt Clarissa, who was good at jazz clarinet, and began to learn clarinet under her aunt's enlightenment. With a keen sense of music, she suddenly found that life should be so wonderful, so strange emotions grew in her heart. Martin saw his sister's friendship with his daughter getting deeper and deeper, but his heart was full of doubts, because Martin had been at odds with Clarissa since childhood. Ten years later, Lala's excellent performance made the teacher suggest that she receive professional music education. In order to cultivate lesbians, Clarissa hopes that lesbians will move to Berlin to live with them, and also register lesbians in local music schools. The kind father began to feel the crisis. He found that music seemed to take his daughter away from him, so he took various measures to stop Lala from learning music. Lala is faced with the first dilemma in her life: how to deal with the family relationship with her parents and how to continue her musical dream.

Lala kept secrets from her parents, but the storm broke out at a family gathering. Lala, desperate, moved to Berlin to live with her aunt and uncle Greg, and prepared for the entrance examination of the music school. Lala's parents feel lost and have an extremely subtle emotional contradiction with their daughter.

Unfortunately, after her mother passed away, Lala came home to attend the funeral and realized her responsibility to her father, but she was also very depressed. After a fierce quarrel, Lala decided to leave this home forever and return to Berlin. On the day of Lala's entrance examination, my father unexpectedly appeared and told Lala in sign language that "listening" and "understanding" were different. At this moment, Lala and her father are looking for the intersection of each other's worlds.
