Its owner, Artur Royal, is drawn into the intrigue by his English friend Philip, when he discovers that Alverca, one of his most esteemed employees, is secretly working for Nazi Germany. Royal will have to undergo unforeseen efforts when he decides to disguise himself as a Sevillian in order to extract as much information as possible from Hitler's spy.
