The Price of Nonna's Inheritance (Italian: Ricchi a tutti i costi) is a 2024 Italian black comedy film written and directed by Giovanni Bognetti, starring Christian De Sica, Angela Finocchiaro, Dharma Mangia Woods, and Claudio Colica.
A month later, Anna, her husband Carlo, and their children, Alessandra and Emilio, are at a restaurant waiting for grandma Giuliana, who has an announcement.
Anna is devastated, believing Nunzio is after Giuliana's money and may resort to murder, as his previous wealthy, older wives died suddenly.
Alessandra devises a plan using aconitum, a plant in Menorca that causes death by asphyxiation, simulating a heart attack.
Alessandra hesitates to push Nunzio off a cliff, and Emilio gets accidentally poisoned by aconitum, foiling the plan.
On the eve of the wedding, the family drugs Nunzio with sleeping pills in order to suffocate him with a car exhaust pipe.
