In Reims, a group of women meet every week aboard a strange boat with a dragon head. Sandrine, Rose-Marie, Poups and Fanny don't know each other, but they all have in common that they have been fighting breast cancer. On the advice of their oncologist, Dr. Cuvelier, they will row to prevent recurrence, to rebuild themselves physically and morally, but also to exorcise the fear that lives inside them.
