在一個平常的下午，少年拉著大提琴,如常地無視旁邊刑警做愛的聲音。就在G大調奏完的一剎，一個人頭突然跌入了二人的空間，鮮血劃破了一切表面的平衡。一宗撲朔迷離的命案，一個G字，連繫著六個空虛的都市靈魂，六人由G開始，亦在G終結。資優女生、大提琴手、自閉少年、爆裂刑警、來港妓女、偽善教師，交織出一個抑壓、扭曲、冷漠、絕望的城市。明快的剪接，別具心裁的美術設計，營造出港片罕見日系風格。在這逐漸寧靜的時勢，也能聽得到創作團隊的無聲吶喊。難道GG就是我們的命運?

The discovery of a human head ties a student, a cellist, an autistic teenager, a police officer, a prostitute, a teacher and a dog together in this ensemble mystery, a project from the third edition of Hong Kong government’s First Film Initiative. The directorial debut of longtime assistant director and Fresh Wave Film Festival alumnus Lee Cheuk- pan is a multi-layered, Rashomon-esque thriller that examines the current state of Hong Kong society through a gruesome murder. It’s a twisted thrill ride that will keep audiences guessing to the very end.
