在这部索姆湾谋杀案犯罪片中,索姆灣沙丘出現一具男遊民屍體，背上有獵槍造成的槍傷。德巴克與新同事伯傑負責調查，但他不按牌理出牌的方式刺激到本地人的觀感，造成辦案的困難。
The unidentified body of a homeless man is found in a dune of the Bay of the Somme, a shotgun wound in his back. An accident or murder? The local gendarmes, commanded by Aurore Debac, investigate. But Aurore is assisted by the opinionated Major Paul Beaujour, who's just arrived in the area, has unusual methods and knows nothing about local customs, in particular the special rights accorded to some of the local notables, most of them hunters, members of the very posh Gentry Club, who might be involved in the killing.
