Heart Beats of Long Ago

A feud existed between two Italian houses and it meant disaster to any one of the belligerents to intrude into the opposing house. The Lord of the house gives a feast in honor of the arrival of a wealthy foreign noble, whom he expects to make his son-in-law. The daughter, however, has given her heart to the son of her father's enemy. That he may be present at the festival, she surreptitiously takes her father's signet ring, throwing it to him from the window, which, of course, admits him. (imdb)
