An Italian spy arrives in Huelva bringing classified information that both sides want. The Nazis go ahead and hide it in the German Consulate. Peter manages to contact the Italian and offers him to leave the country, without being very clear about his loyalties. Lucía, after seeing the war room, discovers that there is a team of spies in La Compañía. The British are going to celebrate the King's feast and Francisco invites Lucia, who fears being fired from her when Peter discovers that she is the governor's girlfriend. This invitation brings to light old secrets that implicate Rocío, Francisco's mother, and Cinta, Lucía's mother: she must prevent Lucía from going to the party with her son. For his part, Schneider appears at the party with Hanna, his daughter, who notices the governor. The English will use the party to get the Italian out of the country and Lucía finds herself inadvertently involved in the mission.

The Nazis have blown up the dock and only Lucia has seen the saboteur. But she is devastated by Agatha's death and angry at Peter for putting them in danger. The club's buses reveal that the saboteur will go to Seville, so Peter asks Lucía to accompany him. They will pretend to be married and look for the guy, whom Lucía must recognize. Schneider blackmails Amparo for bringing British spies into the German party and she will pay a high price to save her life. Peter and Lucía will prove to be the perfect "spy marriage."
