Vincent Cassel stars as the cold and calculating leader of a secluded commune in this unnerving apocalyptic psychological thriller. Alexander is like any other kid: playful, curious and naive. He is also a trained assassin. Raised in a hidden paradise, Alexander and his friends dutifully carry out his father Gregori's (Cassell) cold-blooded orders without questioning their actions. But the unexpected arrival of a newcomer soon creates creeping fears which threaten to turn Gregori's idyllic world upside-down.
