Lili is the secretary of the director of a major factory in Düsseldorf, with whom she must do a business trip to Madrid. Lili comes to Spain with several ideas and topics about the activities that a good tourist should develop. But by chance she meets Carlos, single, well-off status and great connoisseur of the "good life" of Madrid, and she falls in love. She also meets several typical characters: the waiter of the bar where she eats breakfast, the shoeshine boy, a taxi driver and a street photographer, with whom she begins to really know Madrid and its inhabitants.
