In a world where there is hardly any life left, Marta must protect her son Samuel from the dangerous world that surrounds them. Everything changes when a curious survivor arrives at her precious home.

Luis Miguel, a 30-35 year old man, unemployed, lonely and with a boring life. He realizes that his Wednesdays are disappearing, or worse, someone is stealing them, and oddly enough there is an association behind all this trafficking in his days. After discovering it, Luis Miguel turns his sad life upside down and begins to fight against the association.

After a wild sex session in a brothel on his 40th birthday, Luis, bitter and haughty, tries unsuccessfully to escape from the blood stain that, without explanation, grows on the sheet over the bulge formed by his lover. Desperation and what he finds under the sheet means that the only option is to jump out the window of the room already full of blood. The blow plunges him into a strange dream in which a particular fairy godmother reminds him of the child that she still carries inside and the need to take care of him. Convinced of the teaching, by blowing out the candles on his birthday cake, Luis wishes to become that child. Beneath the sheets, drenched in blood, he discovers the error of his desire.
