Watch the Hilarious Red Band Trailer for ‘The Little Hours’, Starring Alison Brie and Aubrey Plaza as Raunchy Nuns

Threesomes in a nunnery… what could go wrong?

The Vatican has really loosened its collar in recent years, amending its hardline stance on contraception and even same-sex marriage.

But do not expect Pope Francis to run to a screening of The Little Hours, the R-rated comedy starring Alison Brie and Aubrey Plaza as raunchy, sex-crazed nuns.

A downright sinful, albeit hilarious, trailer for the film just dropped, and the Catholic backlash is imminent.

Production company Gunpowder & Sky offered the following synopsis:

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.

Nick Offerman also stars as a medieval lord, and Fred Armisen plays a priest. Very wicked stuff, indeed.

The Little Hours hits theaters on June 30. Be prepared to head to confession afterwards.
