Watch on Soap2day. In the heart of Saint-Malo, there's a gigantic area, covering 1/3 of the city, off-limits to the public. It's a part of the commercial port that's mainly accessible via an architecturally unusual footbridge that limits access. An inaccessible place that will be the first to disappear beneath the waves in a few years' time. Only strange sounds reach us from afar: whirring, construction noise, sirens wailing... This parallel world is bustling day and night. But it's in the depths of the night that unfamiliar sounds and lights arouse the most fantasies.
