La antena
The movie begins with a pair of hands typing on a typewriter. The denizens of a nameless city "in the year XX" have lost their voices. People communicate by mouthing out words that are spelled mid-air. The only person who has kept the use of her voice is La Voz ("the voice"), a singer working for the sole TV channel broadcast in the city, run by Mr. TV, who desires La Voz. La Voz wears a hood over her head that hides away her face. She has a son called Tomás, an eyeless little kid who nonetheless also has a voice (although this is kept a secret). Tomás lives next door to Ana, whom he one day befriends after a letter addressed to his house is erroneously delivered to hers.
Ana's parents are estranged - he works for Mr. TV as a TV repairman, she is a nurse at a hospital. When Ana loses a "balloon man" owned by the channel, her father and grandfather are fired from the studio. Soon enough, Ana's father stumbles upon evidence that La Voz has been kidnapped, and, together with Mr. TV's vengeful son, they set out to spy on Mr. TV. Ana's father pays his ex-wife to let them into the hospital, where Mr. TV and his henchman Dr. Y (a scientist whose lower head has been replaced with a TV screen showing a mouth) subject La Voz to a series of experiments of dubious nature. They plan to use La Voz's unique power to finally subdue the denizens of the city. However, Dr. Y theorizes that a second voice might counter the effect of La Voz's. Mr. TV's outraged son comes out of hiding, is overpowered, and then put away, by his father's henchmen, whereas Ana's father manages to escape with the aid of his wife.
The reconciled couple manage to rescue Ana and Tomás from Mr. TV's henchmen (led by a masked, malformed man referred to as "the Rat Man") and meet with the grandfather. Since Mr. TV is going to broadcast La Voz's voice and thus subdue all citizens, they have to broadcast a second voice to counter the effect. The grandfather suggests using an old station, The Aerial, abandoned in the outskirts of the city, in the snowy mountains. Tomás, Ana and her parents don inflatable suits (equal to those donned by "balloon men") which send them floating up in the sky. Just as the grandfather finishes elevating them, the Rat Man and his henchmen arrive and shoot him. The family are then propelled away into the mountains.
Meanwhile, Mr. TV and Dr. Y initiate the broadcast during a boxing match. The citizens become hypnotized and subsequently fall asleep. Words then start oozing out of their bodies - the machine that sucked out their voice now takes their words out of them. In The Aerial, the Rat Man and his henchmen storm into the station, stopping short Tomás's transmission. Ana's father and the Rat Man fight over a gun and stumble into a secret room in the station that reveals The Aerial's director, a young girl fitted inside a glass orb that oversees the production of the drugged food that keeps citizens under Mr. TV's control.
The gun goes off and kills The Aerial's director, who turns into an old woman after dying, and Ana knocks down the Rat Man. Back at the lab, Tomás's transmission sends Dr. Y into a choking fit and is finished off by Mr. TV. The transmissions counter each other and the citizens wake up, now able to use their voice (albeit without being able to speak). In the end, the family comes out of The Aerial, trying their new voices.
