Everyone believes Sister Maria is a kind young nun devoted to helping Father Benedict with endless errands.

Hidden beneath her holy disguise, she spends her days maintaining the illusion and her nights causing harmless mischief, from stealing shoes to tickling unsuspecting villagers' toes. But when someone begins noticing the cracks in her carefully crafted lie, Sister Maria must decide whether to protect her secret or trust the first person who's ever truly seen her.
