De zeventienjarige Elina ambieert een carrière in de rapscène. Doordat haar moeder een nieuw vriendje heeft, verruilt ze noodgedwongen haar vaderland Finland voor Frankrijk. Ze ontmoet haar stiefzus Sofia, een leeftijdsgenote en charismatische balletdanseres. Deze leidt een dubbelleven vol drugs en jongens. De vriendschap tussen de meisjes verandert stilaan in een machtsspelletje met grote gevolgen.
