Fa (Cherry Ngan) works in her family's tofu store but dreams day and night of being a professional dancer. Signing up for the college dance crew BombA once she got admitted into university, Fa turns into the school's new emerging hip-hop star overnight and quickly hits it off with crew captain Dave (Lokman). After being introduced to Tai Chi by Leung (Babyjohn), Fa looks to incorporate the traditional martial arts into her dance but is devastated by leg injuries. Going head-to-head against BombA's strong rival Rooftoppers, Fa finds it hard to believe what Stormy (Tommy "Guns" Ly), Rooftoppers' leader, has in store for her, and the lengths to which Stormy goes in the name of dance.
