The series "3615 Monique" is a French dramedy about the creators of the world's first erotic dating service. The events take place in 1980, when the company "Vidéotex" enters the communication market in France - an instant messaging service. While other businessmen timidly test the waters in this direction, three poor students from the outskirts decide to take action. They revolutionize the erotic industry and open a service for exchanging explicit messages.
