In an American suburb of the 1950s, a young woman named Joan becomes the leader of a group of rebellious girls that resembles more of a gang than a club of friends. Fleeing the monotonous and oppressive lives imposed on them by adults, Joan and her crew embark on a series of pranks that quickly escalate into serious crimes. From thefts to bar brawls, their thirst for adrenaline leads them down a dark path, where violence and anarchy become part of their routine.
As tensions rise, the police start investigating their activities, and the girls must work hard to maintain their wild lifestyle. However, chaos manifests not only externally; Joan's friendship with her companions is put to the test as jealousy and betrayal emerge. The atmosphere becomes especially heated when the local boys, drawn in by their wild way of life, get involved in their misdeeds, leading the story to an explosive climax.
The film explores the internal struggles of these young women, their conflicts with authority figures, and their desperate desire to break free from social expectations. As the world they have created begins to crumble, Joan finds herself at a crossroads that will force her to confront the truth about her reckless life and the consequences of her choices.
