在这部残酷琴迷犯罪片中,皮尔塔迪尔白天从事劳工工作，和生病的父亲同住。他忘不了童年时和母亲在海边的回忆，只有借助谋杀才能证明他的存在。某天他在书店遇见并爱上钢琴家劳拉……当连环杀手遇上存在主义，影迷目光第一时间望向法国，犯罪小说家薛利埃以镜头代笔，接棒查布洛，又接棒积葵奥迪亚。图卢兹青年皮耶回望沙滩的快乐时光，小子戏言要屠龙，要保护妈妈跟妈妈结婚；现实人生却是照顾脑退化的父亲，干没满足感的工作。他随意选择受害人却细心行凶，从中认活自己，讽刺是行凶的地窖是祖母二战时用来藏匿犹太人，当他遇上罗莉，温馨与杀意互换。当存在主义遇上连环杀手不独是通俗文学式罪与罚解话，更是从小窗爬入黑暗内心，沉着气的浏看。
