Mangiacake

Tessa and Marie, move back home with their mom and devoutly Catholic Nonna (grandmother). The sisters' broken relationship turns into a tug-of-war over who is to be the most important family member in the house. Mom and Nonna are forced to leave home in order to escape the constant fighting between the two sisters. With the sisters alone, things go from bad to worse for the girls and they're finally forced to come to terms with their special sisterly relationship following a trip to church.
