A washerwoman works so long for the same bosses that she gets to like their young son very much. One day she is unjustly accused of robbery, and dismissed. She suffers in her loneliness, until the day she hears that the boy is terminally ill, and there's no medical hope for him. She comes back and sits by him, praying to Saint Thérèse de Lisieux - and the miracle happens.
