A kitten named Tino looked at the day and night of Paris. During the day, she is a little girl Zoe (voiced by Oriane Zani) pet, bringing her small gifts every morning. Zoe's parents are both police officers. Her father was killed by the biggest villain in the city, Victor Costa (Jean Benguigui). Mother Jeanne (Dominique Blanc voice) vowed to bring Costa to justice, gradually ignoring her care for Zoe. Little Zoe sealed herself off without saying a word. Every night, Tino jumps out of the window to look for Nick (voiced by Bruno Salomone), another friend who lives in the night. Nick is a quick thief, he is elusive and skillful, but Tino is his only friend. Tino shuttled back and forth, becoming a wonderful link between two completely different people. One night, Zoe slipped out of the room with Tino, only to encounter a Costa gang that tried to rob the stone statues of the exhibition hall. Zoe, Nick and Jeanne were all involved.
