Emily (Kathryn McCormick), the daughter of a wealthy businessman, arrives in Miami with aspirations of becoming a professional dancer, but soon falls in love with Sean (Ryan Guzman), a young man who leads a dance crew in elaborate, cutting-edge flash mobs. The crew, called the MOB, strives to win a contest for a major sponsorship opportunity, but soon Emily's father (Peter Gallagher) threatens to develop the MOB's historic neighborhood and displace thousands of people. Emily must band together with Sean and the MOB to turn their performance mobs into protest mobs, and risk losing their dreams to fight for a greater cause.
