Watchman Guangdong and his wife Baoyan have devoted their lives to their only son, Zhaohang. When he leaves China to pursue a music career at the Estonian Academy of Music and Theatre, the couple must confront the emotional void his absence creates. Through phone calls, they try to guide Zhaohang from afar, but his journey is shaped by both his deep desire to please his beloved father and his own personal ambition.

Vahimees Guangdong ja tema naine Baoyan on pühendanud elu ainsale pojale Zhaohangile. Kui poeg aga Hiinast lahkub, et õppida muusikat Eesti Muusika- ja Teatriakadeemias, peab abielupaar seisma silmitsi emotsionaalse tühimikuga, mille tema puudumine kaasa toob. Nad püüavad telefonikõnede abil Zhaohangi kaugelt suunata, kuid poja teekonda kujundavad lisaks soovile isale meele järgi olla ka tema enda ambitsioonid.

Guangdong et sa femme Baoyan ont organisé toute leur vie dans le seul but de soutenir la formation de leur fils unique, élève à la prestigieuse académie de musique de Pékin. Mais maintenant que Zhaohang donne enfin corps au rêve de ses parents et part à l’étranger pour mener sa carrière, ils vont devoir affronter et donner sens à cette absence.
