According to the other proverb, there are seven women for every man in the world—Andrea has them all at home, and none of them is easy to deal with: his grandmother Matilde, once a professor of astrophysics, is now suffering from dementia and depends on her live-in caregiver Bogdana.

His mother Vittoria, administrator of 11 condominiums, is the undisputed master of the house, nicknamed Sergeant Hartman (after the Full Metal Jacket character) for her rigorous ways.

Beatrice, who became a notary at age 22 (at the same time winning four consecutive wet T-shirt contests), is a perfectionist with a tendency to alienate people through her arrogance.

However, six months into their relationship, as she is spending the night at Andrea's place, tensions arise: Grandma walks in on the couple at night, Vittoria makes the two cancel a planned trip to the beach so Andrea can run some errands for her, Beatrice criticizes Roberta's cooking, Bogdana destroys Roberta’s computer with her thesis on it, Veronica scratches her car and has it towed for being parked in front of the family's garage, and Federica exchanges her dog for another by mistake.

Beatrice’s fiancé leaves her at the altar, as he can no longer bear a woman as flawless as her, which destroys Andrea's hope of another sister moving out.

He encourages Federica's assistant (and potential father of the child she is expecting) to make a move towards her, and does the same to the concierge of the condominium, who has long held feelings for Vittoria but never had the courage to express them.
