Engineer Henri Poincaré works hard to try and bring up the frigate HMS Lutine which went down almost 200 years before with millions worth of gold in its belly. As a reward for his hard work, Henri takes a break and hikes at low tide across the Wadden Sea. Henri gets to know his guide, Liesel Kraus who is a director at Kraus Steel and is still haunted by a violent history and corrupting wealth.
