改编自1953年乔治西默农(Georges Simenon)的小说，描述一名侦探破获系列离奇案件的惊悚故事，镜头画面风格非常特别，具有法国传统电影的风韵。本片原作小说是法国天才快手作家乔治西默农创作的《梅格雷探案》系列的其中一部，某些情节参考了他的其它作品。法国导演塞德里克康被看作是法国电影界最有前途且最难归类的青年导演，他的前几部作品已经为他在国际影展上赢得了一定的口碑。他是法国影坛的叛逆者，一直反抗着那些陈旧的规范准则，尽管他坚持认为自己是作家导演，但他的许多影片都是改编小说之作。另外，本片的男主角尚皮耶达夫桑是各大电影节的常客，而女主角卡洛波桂则是著名的性感模特。

After ten years of doing nothing, Orel and Gringe are in their mid 30s and they struggle to finish their first rap album. Their texts are mostly sex jokes and booze stories and reflect the everyday life they have in a small town from France. The problem is that they never really finished a song and when their producers want to meet, they have to face a new challenge : finish their first song in the next 24h. Their old issues, the fear of failure, their alcoholic friends and annoying girlfriends won't help them to do so, or will they ?
