Aged 21, Maria Lindberg suffers a cerebral haemorrhage during a boxing match. She makes a miraculous recovery but her true fight begins when she wants to return to the ring. The Swedish Boxing Federation won't let her fight because of the accident, her mother is reluctant to even hearing Maria talk about boxing, and wherever in the world she travels to fight, it seems like someone is trying to stop her, as if a shadow was following her every step of the way.
