A private and secluded island, five people claiming a mysterious inheritance, no way out… A small Breton island, a private island, without any access to the outside world. It is on this island that Hugo, Harold, Eugenie, Victor and Naima come following the invitation they received. They don’t really understand why they are here, but this legacy story intrigues them a lot.
When they arrive they get to know each other, they realize that they have absolutely nothing in common, they don’t come from the same town, they don’t come from the same family, they don’t have the same origins, they don’t have the same age, they don’t have the same jobs. They don’t understand how such different people can be bound by the same inheritance. But very soon mysterious events will show them that they should have been cautious.
Why do Naima, Eugénie, Hugo and Victor find themselves confined on the island of Saint-Riom? Who is this mysterious ancestor whose identity is jealously kept secret? Who is secretly pulling the strings of this mysterious plot?
