A peaceful island turns into a prison, when a group of armed activists take the whole population of the quaint, isolated place off the coast of Brittany hostage one morning. They are highly organized – yet their motives remain a secret. Who are they? What do they want? Who can stop them? There’s only one thing Alpha, their leader, hasn’t taken into account: Five passengers of the shuttle that links the island to the mainland manage to escape and hide. As the islanders face this extraordinary, deadly situation, secrets surface, sources of conflict. But who among them will become a hero, a coward, or a traitor? Who is the stranger who returned after ten years of absence? Will Chris, Dorian, Kelly, Mado, Alex, and the others succeed in thwarting Operation Ocean Storm? Will Candice find the love of her life? And are the goals of the activists really as bad as their actions make it seem?.
