回复 :Vienna, 1920. The Austro-Hungarian Empire has collapsed. Peter Perg returns home from the Great War, after seven years as a Russian POW. Vienna is experiencing the multiplicity of political, social and artistic freedom, but also the rise of anti-democratic movements, insecurity and unemployment. Peter, a former police inspector, feels like a stranger in the new Austrian Republic. While wanting to leave town, Peter is confronted with the murder of one of his former comrades. He decides to stay and instead bring the killer to justice. His ally is Dr. Theresa Körner, a determined and cool-headed forensic doctor. The two are linked not only by this case, but also by a deeper, shared history. As their investigation progresses, they realise that they are not just up against a systematic killer, who tortures his victims, but also face disapproval and intrigue from within the police force. Though determined to solve the crime, Peter, harbouring his own secrets, increasingly becomes tormented by existential questions: What is truth? What is heroism in the time of war? And all the while he fails to see the mounting danger before him.

回复 :影片故事背景一如上集，主要人物布迪警长亦由上集的罗伊·谢德扮演，但是今次出现肆虐艾密迪海滩的大白鲨，却是一条满含恨意，一心前来报“杀夫之仇”的母鲨。
