德文·巴特勒是一个八岁的孩子，他梦想成为一名警察。他看警察的电视节目，知道警察的程序，和他的朋友雷玩警察和强盗的游戏。一天，他在仓库里四处窥探，目击了一起谋杀案。他去找警察，警察想要这些信息，但直到他们让德文成为警察才会得到。然后，警察把他和老练的警察尼克·麦肯纳(Nick McKenna，讨厌孩子的人)组队，两人在一系列喜剧事件中组队寻找凶手。
Devon Butler is an eight-year old who dreams of being a cop. He watches police TV shows, knows police procedures, and plays cops and robbers with his friend Ray. One day, while snooping around in a warehouse, he witnesses a murder. He goes to the police, who want the information, but won’t get it until they make Devon a cop. The police then team him with veteran cop (and child hater) Nick McKenna, and the two team up in comic series of events to find the killer.
