La antena (The Aerial)

An entire city loses its voice as it endures the throes of a long, harsh winter. The evil, unscrupulous Mr. TV, sole owner of the images on the local screens and of a wide range of goods made under his own personal label, implements a sinister secret plan to eternally dominate each of the souls inhabiting the place. To achieve his wicked ends, he pays for the creation of a dangerous machine transmitting hypnotic TV images inducing compulsive purchase of the products bearing his brand name.
