Nobody sees it

Rebecca Young is an 18-year-old girl and has a form of rheumatism. Because of that, she is very sick. However, this is not standing in her way of following her dreams. She wants to audition as a parade performer at Disneyland Paris, but is this such a good idea? People along the way will try to stop her, mess with her head, and convince her she is wrong for trying. Will they be successful or will Rebecca go through with it? Is her sickness really standing in the way?
