Miquel Mascarell is detained by the police, who want to know why his name appears in the appointment book of the son of a journalist friend who was executed by the regime. The young man is acused of the murder of a Spanish diplomat. Miquel feels obliged to investigate the incident to demonstrate his own innocence and also to help the youth. The diplomat had just been expelled from the United States. Why? In the days when Spain was making every effort to be recognized at an international level, particularly by the United States, and when the "sale" of the military bases at Morn?, Zaragoza, Torrejn? de Ardoz o Rota looms on the horizon, Miquel discovers that the Spanish embassy in Washington is a sieve to North American intelligence. Too much so for the Russian secret service to keep unchanged: American bases in Spain could destabilize the map of Europe.
