Ver en Cuevana. Alex, an experienced surgeon, makes a mistake in the diagnosis of his seven-year-old godson. The boy dies on the operating table. Stunned, the man tenders his resignation. One autumn morning he is sitting on the riverbank in a favourite place where he used to fish with his godson. Suddenly he notices the figure of a shapely semi-naked girl emerging from the fog. She is shivering with cold. Alex spontaneously offers his help, and thus becomes part of an incredible adventure story.
