May 2007. When an American treasure-hunting company uncovers a shipwreck containing the greatest underwater trove ever found, the world is captivated by their discovery. But over in Spain, a group of low-level government officials surmises that the sunken ship is in fact an ancient Spanish vessel. Thus begins a legal and political thriller, pitting a group of idealistic diplomats against a rich and powerfully connected treasure hunter, in which vital cultural artifacts and hundreds of millions of dollars hang in the balance.

Cartoonist Paco Roca and writer Guillermo Corral bring a cinematic flair to this graphic novel, combining threads of Tintin-inspired seafaring adventure, political intrigue, tense courtroom drama, and, in the midst of it all, a budding romance. A gripping dramatization of a little-known, unbelievable true story of money, political power, and cultural heritage.
