Victorian era. After a masquerade ball, a heavy rain forces two strangers to take refuge in a dark cave by a fire. Aurelian, the heir to an ancient family, thinks that his companion is a mysterious girl in a mask. He admires her tenderness and mystery, not suspecting that in fact, before him is a young man with the image of a girl. Under the sound of the rain, they share the silent warmth of the fire, and Aurelian quietly admits how rarely he manages to meet such a soul.
