个性张扬的街头嘻哈与高贵典雅的芭蕾可以在舞台上完美的契合，就像泰勒（钱宁 •塔图姆饰）与诺拉（珍娜•迪温）的结合一样。这是一个奇迹，还是一种宿命。 　　泰勒是来自巴尔的摩的底层社会的反叛青年，诺拉是就读与贵族艺校的优秀的芭蕾舞学生。诺拉要参加的高级舞蹈比赛，需要一个舞技超群的舞伴，而泰勒刚好因为被罚在艺术学校社区服务而闯入诺拉的视野。泰勒随意自如的街头舞蹈吸引了诺拉，舞台上的一次次合作，让这两个同样执着于艺术的孩子擦出律动的火花。 　　两条原本平行的直线，交汇于舞蹈的光辉。In Baltimore, the troublemaker and street dancer Tyler Gage lives with his foster parents in a lower class neighborhood. His best friends are Mac Carter and his little brother Skinny Carter and they used to hang around together, going to parties and stealing cars. After being expelled from a party, the trio breaks in the Maryland School of Arts and commits vandalism, destroying the stage. Tyler is arrested and sentenced to 200 hours of community service in the school and Director Gordon assigns him to help the janitor cleaning the place. One afternoon, the ballet dancer Nora Clark sees Tyler dancing in the parking area and when her partner Andrew has a strain and Tyler offers to help her in the choreography, she accepts the offer; they rehearsal and become close to each other while Tyler becomes friend of the students Miles Darby and Lucy Avila. When Andrew returns, Tyler that is known for quitting everything he starts gives up dancing and leaves Nora alone. After an incident, Tyler has to decide to follow his dream or return to his life of rebel loser.
