他，特洛伊（扎克•埃弗隆），是学校篮球队队长；她，加布里埃尔（瓦妮莎•哈金斯），是高智商的优秀学生。两个本来自不同世界的少男少女，却因为音乐和舞 蹈，擦出了耀眼的火花。从除夕假期的卡拉OK比赛，到一起参演学校音乐剧，从纷闹的暑假打工记，到高中小儿女的争风吃醋，这对经历了风风雨雨的高校恋人， 也终于进入了高中最后一学年。
即将毕业的他们，很可能面临考上不同大学、各奔东西的命运。放弃各自梦想中的大学，未免不太实际。而浓烈的少年恋情，又会不会被扼杀在不确定的未来里？在 “野猫”篮球队全员和其他好友的助阵下，特洛伊和加布里埃尔决定以自己的心路历程排演一出音乐剧，怀念高中的美好时光，唱出面对未来时心中的担忧与期待。
篮球冠军赛、毕业舞会、春季音乐剧...，繁忙的活动中，动听的音乐和华丽的舞步让特洛伊和加布里埃尔暂时忘了离别，在相处和排练中珍惜着毕业前快乐的每 一天。除了好朋友查德、泰勒、瑞恩和刁蛮的夏帕，野猫篮球队的高二新秀们，也将加入这个青春飞舞的梦想队列。音乐剧重头戏就将轰轰烈烈的上演，年轻，没有 什么不可以！
英国，“哈利波特”迷的大型集散地之一，一部第一次跃上银幕的续集，居然已经打破《哈利波特4》的预售票房佳绩，创下令人惊异的新纪录！到底是哪家的“无 名小子”，竟然有如此牛的冲击力？答案很简单：《歌舞青春》第三集，少男少女们趋之若鹜的迪斯尼产品之一。
一向在迪斯尼电视频道风靡的电视电影，怎么反倒越演越烈，有了搜刮大银幕的豪气？倘若你敢质疑迪斯尼的老谋深算，今年二月的票房榜单大概可以让你恢复记 忆：不过在数百家影院上映的某3D演唱会纪录片，竟然轻松突破重围，并接连刷新历史开画纪录和单厅平均成绩纪录！这一切只不过是因为它冠上了“汉娜•蒙塔 娜”的名字，而《汉娜•蒙塔娜》正是迪斯尼电视频道高踞收视率榜首的少女电视剧。这当然不是迪斯尼第一次将流行节目向大银幕移植。对于青春偶像成堆的米老 鼠俱乐部，这只不过是它光荣榜上又一个成功的痕迹。既然如此，身为迪斯尼史上最成功的青少年电视电影之一的《歌舞青春》系列，又怎可能安于屈居小荧幕冠 军？
炫目的舞蹈，动人的旋律，唯美的画面，搭上百听不厌的原声大碟，集齐俊男美女的原班人马，第一次跨界大银幕的《歌舞青春》系列，马力十足。除了奉上更宏大 的场面、更精美的画面、更易于传唱的歌曲，标配老少全杀的G评级，就连用户近亿的Myspace也破天荒第一次，为之推行了史上最大规模的电影宣传活动， 看这势头，势必是要在在万圣节档期，掀起不可控制的热潮！
