Prison Island

Armed activists take the inhabitants of the small Breton island of Penhic hostage. Five passengers on the shuttle between the island and the mainland manage to escape, and a relentless manhunt begins to find them.

Ahmed, the postman from the mainland, arrives on the island of Penhic as he does every week. Who, among the inhabitants or the shuttle escapees, will manage to tell him that the islanders held prisoner by the armed group are in danger?

Who among the islanders will become a hero? Who will be a coward? Everyone has been suspicious of each other since they discovered there is a traitor among them. However, hope is rekindled with the unexpected arrival of a police shuttle.

Yannick tries to escape the activists to find Alex, whose return will not please many people. Meanwhile, the launch of the mysterious Océanite Tempête operation approaches.

The prisoners of Penhic discover who betrayed them. Their only hope of escaping the armed group now rests on the last two survivors of the shuttle, a grandmother and a teenager.

All seems lost for the islanders of Penhic. All the survivors of the shuttle are dead or imprisoned. The activists can now launch their operation, and Penhic is about to make headlines around the world.
