Lisbon, early 1940s. The neutral port town is an open door to freedom, for those who are escaping the Nazi occupied France and eastern European countries, and a war field for spies of every description. Lisbon became a cosmopolitan town, where the Duke of Windsor, Primo de Rivera, Pola Negri, Leslie Howard, Walter Schellenberg and Juan Garcia are often together in the luxury hotels and night-clubs. Espionage and crime go hand in hand, despite of, or encouraged by, the Portuguese secret police.

Miguel (Luis Miguel Cintra) is lucky that his income will only level off if he neglects his business as a financier, and his wife and family will be well supported. Why? Because he has begun hearing noises that no one else hears, noises that bother him a great deal, and that make it impossible for him to bear human society. His wife (Jessica Weiss) is thoroughly put out by this radically changed behavior in her formerly good husband, but though she considers leaving him, she stays by his side. Deep in the mountains, Cecelia (Rita Dias), a devout, pure young cowherd, has been brutally raped by an old man. Her boyfriend (Pedro Hestnes) has killed the rapist, and fled the area. As a result of the rape, Cecelia is pregnant. One day, while driving in the mountains, Miguel gives Cecelia's boyfriend a ride. The two of them chance upon her sitting amid the rocks with her infant baby.

This Portuguese movie directed by João Botelho, is part of The Four Elements series. This is the second episode, The Air.
