FELIX, 12, is a loner. At school just as much as at home. His mother LYDIA bothers him with her extreme care and his father NORBERT, a police officer, is hardly getting close to his introverted son. Since Felix doesn’t communicate, his parents don’t even know he fell in love with the deaf-mute girl LENA; he has been chatting with her on the internet for the past weeks. And now he is in trouble: she absolutely wants to meet him but he pretended being deaf-mute too. To maintain this lie, he practices sign language diligently.
