I protest mod sin mors evindelige indblanding løber 15-årige Mia hjemmefra for at drive rundt i Københavns gader. Hun mister sin pung til lommetyven Zack, hvis bande vil skaffe penge til et ungdomshus. Mia optages i fællesskabet og forelsker sig i Zack, hvilket strider imod gruppens regler. Samtidig begynder Mia at dyrke sit talent for at løbe hurtigt. Måske en mere lovende karriere end at stjæle dankort?

Mia, 15, is at odds with everyone. School is hell and her mother is always on her back. Mia is only at peace when she is running - something she is good at. On a downtown shopping street she meets Zack, 16, who runs with a gang of kids who want to become parent independent and live as pickpockets. Mia joins them, but finds the pressure difficult. Moreover, the police have their eye on them. Mia has a choice, to keep ignoring her problems or face up to them.
