在这部普罗旺斯谋杀案犯罪片中,法国南部一家大型屠宰场和肉类包装厂发现了一具男尸，脖子上挂着写着「他们该受苦吗」的标签。
这是年轻探长Samira Masson的第一个案件，她怀疑犯案者是某动保协会。这阵子以来，该协会一直藉由媒体炒作来反对该屠宰公司。但查明后发现死者是一名卧底警察，所属的是鲜为人知的兽医监视部门。政风处指挥官Etienne Barjac随后被派去与Samira一同调查。
The corpse of a man, a bovine tag attached to his neck with the words \"Can they suffer? \"is found in a large slaughterhouse and meat packing plant in the Manosque region. The suspicions of the young inspector Samira Masson, whose first investigation this is, naturally lead her to an association for the defence of the animal condition which had been orchestrating a media hype against the company for some time. But the corpse turns out to be that of an undercover cop, belonging to a genuine and little-known division of the police, specialising in national veterinary surveillance. Etienne Barjac, commander of the IGPN, the police force, is sent to investigate.
