Medieval nuns Alessandra (Alison Brie), Fernanda (Aubrey
Plaza), and Ginevra (Kate Micucci) lead a simple life in their convent. Their
days are spent chafing at monastic routine, spying on one another, and berating
the estate's day laborer. After a particularly vicious insult session drives
the peasant away, Father Tommasso (John C. Reilly) brings on new hired hand
Massetto (Dave Franco), a virile young servant forced into hiding by his angry
lord. Introduced to the sisters as a deaf-mute to discourage temptation,
Massetto struggles to maintain his cover as the repressed nunnery erupts in a
whirlwind of pansexual horniness, substance abuse, and wicked revelry.
