At a maritime auction in Barcelona, Merchant Marine officer Manuel Coy sees an intense bidding war erupt over a seemingly innocuous 18th-century atlas. The auction winner is the beautiful Tánger Soto, who is obsessed with a Jesuit ship sunk by pirates in the 17th century. Joining forces, Tánger and Manuel hit the seas in search of Dei Gloria and its precious, yet unidentified, cargo.
