富家小子查理·巴特利（安东·叶利钦 Anton Yelchin 饰）同时是一位点子奇多的中学生，因此履出状况的他常常被各个私立学校拒绝甚至开除，迫于无奈，父母只好让查理进入一所鱼龙混杂的公立学校念书。初来乍到的查理难免被学校里的小霸王欺负得鼻青脸肿，然而很快，鬼马的查理就为自己的小聪明找到了的用武之地。当发现身边的很多同学都需要找人倾诉和寻求开导时，查理摇身变作校园里的心理咨询师，在男生寝室门口挂起了自己的小招牌，专门倾听同学们的苦恼，并给出意见甚至是草率地开起了药房。这个小小心理师的角色不仅给查理创造了一笔不小的财富，也让他成了新学校的宠儿。然而，看似单纯的校园生活可并非想象中那么简单，查理的“小生意”是否一帆风顺，又会有什么麻烦等着他呢？Although cheerful, friendly, intelligent, well-dressed, authentic and wealthy, Charlie Bartlett has problems. With his father gone and his mother loopy and clueless, he's been expelled from every private school for his victimless crimes. Now he's in a public school getting punched out daily by the school thug. He ever longs to be popular - the go-to guy - and the true crux of his troubles is that he invariably finds the means to this end, whatever that might be. At Western Summit High, he makes peace with his tormentor by going into business with him - listening to kids' problems and selling them prescription drugs. Charlie's a hit, but attraction to Susan (daughter of the school's laissez-faire principal), new security cameras on campus, a student's overdose, and Charlie's open world view all converge to get him in serious trouble. Can this self-made physician possibly heal himself and just be a kid?
