马岱奥•加蒂是一名电视记者，在抢夺头条新闻的时候，他从来都是一把好手。然而，一场悲剧彻底将他击垮：儿子在去米兰的一次旅行中，由于嗑药过量而死亡。马岱奥说服台长派他对致幻剂进行全面的调查和报道。他联系了米兰警察特别行动队，和摄影师一起假扮行动队员拍摄并记录了真实的情况。与此同时，她在罗马的妻子正在焦急地等待另一个孩子的诞生。"Sbirri", Italian slang for the police, is the story of a well-known TV journalist who after the death of his son through ecstasy, decides to follow the drug squad in their fight against drug trafficking in Milan. The film takes us on his "real" journey in the world of drugs and his desperate search to find a valid reason, someone to blame for his son's pointless death and at the same time, for his sense of inadequacy as a parent. It's a journey in this incredible underworld where people from all social classes and thousands of young people are being constantly entrapped and where unknown heroes every day put their lives at risk in their battle against crime. All that is shown in the film is true.
