Track 29 (1988)

A doctor's wife tires of his obsession with model trains, and spends her days wondering about the son she gave up for adoption at birth. While eating at a roadside café, she encounters a British hitchhiker, who turns out to be her son. They spend time together trying to find a bond. The son begins to hate the husband, and the wife begins worrying about the safety of her husband and his train set.
