Lucía, an active little girl, looses a tooth. Santiago, her father, is an out-of-work boss, and her mother, Pilar, is a successful but overworked architect, reassure Lucía, by telling her that the Hairy Tooth Fairy (a mouse named Pérez) will come to her bedroom to collect her tooth, leaving some money in its place. A mouse who had been monitoring the situation tells another mouse, who in turn tells another mouse until finally the news reaches Pérez, The Hairy Tooth Fairy, who lives in a boat in the port along with hundreds of other mice. They receive the teeth that he collects, and then clean, shape and polish them so that they can be transformed into shiny round pearls. These pearls are then carried through the citys sewers until finally they reach the jewellers owned by Morientes, where an old friend exchanges them for their weight in gold.

An architecture student is obsessed by his girlfriend. When she is invited to go alone to a party sponsored by her company, he becomes paranoid. He arrives at their place unexpectedly and finds a man hidden under their bed. He follows the man trying to find his name and occupation, along a night full of incidents and misunderstandings.
