In Miami, a flash mob, later identified as "The Mob", shuts down Ocean Drive briefly by cutting off the streets with retro convertibles and dancing on cars to music blasted by DJ Penelope. A few hours later, Sean Asa, Eddy, and Jason Hardlerson, the leaders of The Mob, watch their latest flash mob air on the television news in a restaurant kitchen of the Dimont Hotel where they work as waiters. Aspiring ballerina Emily Anderson tries to get a bartender's attention but ends up preparing her own beer. Sean, who is immediately smitten by her, asks for a beer. The two engage in a dance battle that ends with Emily suddenly running off when she sees her father's business partner. Emily and her father William Anderson argue over breakfast at the Dimont Hotel. Sean recognizes her but Emily distracts him to avoid him. In an angry fit, Emily storms off, and Sean follows her into the hotel's ballroom, where Emily begins a fast contemporary dance, oblivious to Sean's presence. After Emily notices Sean and warms up to him, she explains that she's trying to nail an audition for the prestigious Winwood Dance Academy Company. Sean advises her to incorporate faster, more interesting moves. The next day, Sean reveals to Emily his participation in The Mob by asking her to attend their next flash mob, which leads to them taking out a boat and falling asleep on it. However, when Emily's father plans to develop the slums, destroying Ricky's bar, Sean convinces not to expose him. Instead, The Mob protests the plans, with their dance being a huge hit. Eddy finds out that Emily is William's daughter and reveals her connection to his boss, William. Emily fails her audition for the troupe due to her performance falling flat, but she adapts her piece as a solo after Sean is arrested for saving Eddy. Ricky bails Sean and Eddy out of jail and helps them make up with their friends, including members from The House of Pirates. Sean and Emily then perform the original audition piece together. Seeing his daughter so happy, William decides to build the community up rather than tear it down.
