Rules for 50

Rose Levenson is a 17-year-old ballerina who is watching her mother slowly die from Huntington's Disease. Which means, Rosie has a 50/50 chance of having the disease herself. Determined not to allow herself to pursue dreams that could be dashed if she does have the disease, she refuses to consider love or go after her dream of dancing professionally. That is until she meets a boy who changes her mind.
