Vincent Elbaz as Vincent Libérati, the protagonist, a French covert agent recently diagnosed with a brain tumor who relocates to Marseille to be closer to his estranged family, who know nothing about his illness or his job and believe him to be a burglar alarm installer.
A potentially fatal brain tumor forces Vincent Libérati to abandon the glamour of a globetrotting secret agent's life and return to Marseille to be close to his teen daughter Lola and ex-wife Alexandra. In order to receive an experimental medical treatment, Vincent agrees to join Hydra, a confidential organization set up by secret services to fight organized crime on the French Riviera with illegal means. Meanwhile his personal life isn't rosy either as he still isn't over Alexandra and is still trying to figure out Lola.
