After a well-watered party on the day of his 18th birthday, Cédric has a spectacular and serious car accident. On board the sports car is Sarah, her 17-year-old childhood friend. For the two seriously injured youngsters, as well as for their parents, life falls that night. In addition to the physical legacy, which will leave Sarah severely handicapped, is the beginning of a medical, legal and emotional battle that will draw members of two families who were once friends against each other.
