 Blue Bird is a film about Merel, a thirteen-year-old girl. One day she finds herself being bullied. By the children in her class, in the train, in the swimming pool where she swims with her younger brother Kasper who has a handicap. The bullying starts suddenly, out of the blue, for no apparent reason. It makes her hard and gives her life a push in the wrong direction. We follow the emotions of this young girl as she gets lost between childhood and maturity while the bullying hardens her and pulls her down.
