Freshman Jamie Bartlett is frustrated with high-school life. She wonders what it would be like to be popular, where Marco the hunk might notice her and snooty Sawyer would remember her name. To escape the pressures of school, Jamie retreats to her journal, weaving a tale about teen heroine Isabella ("Is"), who's beautiful, self-assured, and popular and can effortlessly zap any pesky person out of her way. When she accidentally turns in her journal as a homework project, Jamie wins a writing contest and finds her books on shelves nationwide. Suddenly she's caught up in the whirlwind of photo shoots and guest appearances and starts to lose touch with her friends and herself. Meanwhile, Is becomes a real presence for Jamie, though no one else can see her. As Jamie's stardom grows, her literary alter ego pops in and out of her life to influence every move she makes. Jamie eventually becomes disenchanted with her new life and in the end must decide whether popularity is worth sacrificing self-respect and true friendship. 一个迪斯尼真人版童话。 杰米（凯·帕娜贝克 Kay Panabaker 饰）是一名十分普通的高中生，默默无闻的她唯一的乐趣就是写日记，她将自己的现实生活掺杂了个人幻想写进了日记里，在那里，她不再是平凡的杰米，而是校园中人见人爱的女王伊莎贝拉（丹妮尔·帕娜贝克 Danielle Panabaker 饰）。 一次意外中，杰米将自己的日记本错当成了作文交给了老师，老师擅自将日记寄给了出版社参加比赛，没想到，杰米成为了比赛中最大的赢家。突如其来的名声给杰米带来了荣耀，却也造成了麻烦，她和家人朋友之间的关系开始疏远。最糟糕的是，杰米渐渐发现，伊莎贝拉这个虚构的形象开始逐渐的入侵到了她的生活之中。
