Giorgio, son of a rich industrialist, is attracted with Lorena, a university student, but she's already engaged to Carlo. After having tried in vain to court her, Giorgio resorts to an extreme measure: taking advantage of his father's absence, he threatens to cause the bankruptcy of the small business owned by Lorena's parents. The girl, to avoid the ruin of her family, abandons Carlo without giving him any explanation and agrees to get engaged to Giorgio. Carlo, having learned from a friend the reason for his girlfriend's sudden change of attitude, must confront his rival and teach him lesson.
