From suburban mom to Mafia don. “Mafia Mamma” follows an American woman (Toni Collette) who inherits her grandfather’s mafia empire in Italy.
Middle-aged writer Kristin (Collette) is dealing with her son leaving for college, her sexist boss, and her recently discovered unfaithful husband. During this difficult time, Bianca — her estranged grandfather's trusted advisor — contacts her with news that he has passed away and she must attend his funeral in Italy.
Despite initial hesitation, Kristin is convinced that this trip could be just what she needs to start healing herself. However, things take a turn for the worse when Kristin discovers that her grandfather wished for her — his last living descendant — to assume the role of boss for the most powerful Mafia family.
Guided by the firm’s trusted consigliere (Monica Bellucci), she hilariously defies everyone’s expectations, including her own, as the new head of the family business.
