A story about the most primal instinct, the instinct to survive. This science-fiction/horror takes place in Catalonia in a likely future. After the dreaded climate change, in a world dominated by hunger, epidemics and fear, and where death is a constant travel companion, a man, an ordinary citizen, loses his 20-year-old daughter. While he is still mourning her death, a stranger who seems to be aware of his misfortune, comments to him that out to sea, at a days journey from the port, there is a house that has survived the catastrophe, which rises above the sea like a miracle. There lies the only hope of finding his daughter.
