Dino is a cat with a double life: by day, he is the companion of Zoé, a girl who has been mute since the death of her father; by night, he roams the rooftops of Paris with Nico, a thief with a noble heart. Jeanne, Zoé's mother, is the police officer in charge of finding the thief responsible for a series of robberies and protecting a statue coveted by Victor Costa — the criminal who destroyed her family. With a noir atmosphere, this animation navigates between good and evil, proving that sometimes heroes appear where you least expect them.
