Nicklas lives a pretty normal teenage life, until one day, not far from graduation, when a gangster from his school beats him up. Nicklas passes out, and the next day when he returns to school he notices that nobody seems to notice him. As he tries to get attention he notices that his actions disappear the moment he has done them. He throws a book and as soon as it lands it's back where he picked it up. He has returned as a ghost, but he can do nothing but passively observe as the police stand clueless to the murder. 我从心底热爱这部电影!!!。 尼克拉斯是一名成绩优异的高中生，他的母亲希望他毕业后进入商学院学习，实际上他厌倦了受人摆布的生活，准备偷偷飞往伦敦参加面试。他与一名外籍学生彼得是好友，在学校因帮其出头与坏学生安娜莉结怨。后安娜莉犯事被人告密被抓，因害怕被其找麻烦，彼得便说成是他以为已经去了伦敦的尼克拉斯做的。然而母亲发现了尼克拉斯的机票，灰心丧气的尼克拉斯从女友的聚会回家路上，正好被愤怒的安娜莉及其同伙重伤。第二天尼克拉斯照常来到学校，却发现自己已灵魂出窍，成了隐形者……
