The residents of an unnamed city "in the year XX" have lost their ability to speak. People communicate by mouthing out spelled words in mid-air. The only person who has preserved her voice is La Voz ("the voice"), a singer who works for Mr. TV's single television station in the city. Mr. TV wants La Voz. La Voz is dressed in a hood that conceals her face. She has a son named Tomás, an eyeless small boy with a voice (although this is kept a secret). Tomás lives next door to Ana, whom he befriends after a letter sent to his home is delivered to hers by mistake.
