The Cure.

Madrid, 1980. When Sole sees Nano come in, bloody and beaten, she already knows what to do. In an improvised infirmary, she tries to mend his son’s wounds. But Nano is getting old, and his body doesn’t heal like it used to. At his mother’s pleas, Nano offers a deal: he will retire from boxing if she, for the first time, watches one of his fights.
