Mia Williams is a volatile and socially isolated 15-year-old. She lives on an London Plan#Sub regions council estate with her single mother, Joanne, and younger sister, Tyler, and is highly antagonistic toward both of them. Mia is a loner, appearing to have had a falling out with her best friend Keely. She provokes Keely's other friends, criticises their dance routine, and head butts another girl. Mia regularly practises hip-hop dance alone in a deserted flat.
