Imagine a family: a policeman father, a housewife mother and four nice children. Now imagine one day at a doctor's appointment, the father of the family learns that he has an incurable disease - Huntington's disease, which will destroy his body and mind in the next 15 years. Yes, the disease is genetic, which means that there is a fifty percent chance that the daughter, a professional ballerina, will no longer be able to dance. And you can forget about your grandchildren, because they are also at risk. How should the O’Briens continue to live? There are several options: you can give up, feel sorry for yourself, get angry, pray, wait for the end. Or we can all together enter into a battle with fate and take from life everything that is due.
