Alfonso (Álvaro de Luna) is retired and still lives in the house where he spent his childhood. He often visits Nanda (Mary González), an old woman who was his neighbor and something similar to his mother when he became an orphan. On one of these occasions, he crosses paths with Martín (Óscar Abad), a young aspiring cyclist. Alfonso then projects his dreams on him and does everything possible to turn him into a professional.
