Val Moretti, the forgotten fourth mafia daughter, is mocked as a weird girl who only tinkers with scrap metal. Her fiancé Dominic dumps her publicly for her sister and tries to force her into a horrible marriage. When brutal foes raid their estate, Val unleashes her hidden deadly skills with guns and machinery. She saves her family alone. Humbled, Dominic begs to re‑engage to save his failing clan. Val coldly rejects him, seizes the armory and becomes Moretti’s most powerful leader.
