Sam, a freelance journalist, decides to investigate the growing phenomenon of disaffected youth joining extremist groups. He infiltrates a group of four young people who have been tasked with the creation of a jihadist cell and whose mission is to destabilise the city centre of Paris.

After a serious sport accident in a swimming pool, Ben, now an incomplete quadriplegic, arrives in a rehabilitation center. He meets with other handicapped persons (tetraplegics, paraplegics, traumatized crania), all victims of accidents, as well as a handicapped since his early childhood. They go through impotence, despair and resignation, with their daily struggle to learn how to move a finger or to hold a fork. Some of them slowly find a little mobility while others receive the verdict of the handicap for life. Despite everything, hope and friendship help them endure their difficulties.
