1767, February. Near the coast of Spain, having entered into battle with pirates, the sailing ship Dei Gloria, belonging to the Jesuit order, dies. The only person who survived, the cabin boy, without having time to fully testify about what happened, mysteriously disappears. All that he managed to report before his disappearance were the coordinates of the tragedy site...Spain, our time. Navigator Manuel Coy, temporarily deprived of the right to engage in shipboard activities for running a ship aground during his watch, meets a girl at an auction who bought an old sea map for a lot of money. Tangier Soto, an employee of a museum in Madrid, is obsessed with the idea of finding the lost ship, which she believes was carrying cargo of extreme importance. She takes Koya as an assistant as an experienced navigation specialist. The girl knows very well that she has crossed the path of powerful and dangerous forces who are capable of doing anything to eliminate their rival. But that doesn’t stop her...In the best traditions of the “Club Dumas” and the “Flemish Board”!
