Siblings Amaia and Aitor are close to turning fifty, do not have children, and since they were young they have lived away from their parents, Kontxi and Iñaki, who are now retired. One summer they manage to fulfil their dream; the four of them get together and go on a cruise called FANTASÍA. Brother and sister allow themselves to be spoiled like children and their parents golden anniversary becomes a honeymoon. Lulled by the sea breeze, time seems to stand still. But beyond the horizon, the walls of their home gradually fill up with paintings and photographs that make up for the growing absences of a reality that forges ahead relentlessly.
