When their family patriarch is stabbed, seven women, each with ulterior motives, become trapped together in a mansion to solve the puzzle of his murder. This is the Italian remake of François Ozon's 8 Women.

A father, who calls himself "open" and tolerant and fights against any form of discrimination, reveals himself as not so liberal when his son announces the engagement to his partner. Overwhelmed by the news, he regresses into the most fierce opponent of same sex marriage, and tries to undermine his son's happiness with a series of embarrassing situations.
