WARNING: SPOILERS

A 77% rating, movie critics? Why? Because it’s an indie, written and directed by the guy who did “Life After Beth,” with an assortment of your favorites from “Parks and Rec” (Aubrey Plaza, Nick Offerman), “Community” (Allison Brie), and “The Big Bang Theory” (Kate Micucci)? Along with indie faves John C. Reilly and Fred Armisen? And Jemima Kirke reprising Jessa from “Girls”? Because you like these people? 

It’s a one-joke movie. It’s 14th-century nuns with modern attitudes and vocabulary. They basically swear the fuck out of the thing. It’s funny the first time we hear it, less so the 37th.

In a convent in 14th-century Italy, Fernanda (Plaza, of course) is the main swearer and tormenter of a well-meaning gardener; Ginerva (Micucci) is a tag-along tattletale, while Alessandra (Brie) just wants to get married—but her father, Ilario (Paul Reiser), doesn’t like the dowry that’s being demanded, so there she stays, embroidering.

Into this not-so-sedate world stumbles Massetto (Dave Franco, “21 Jump Street”), his blouse undone, fleeing his previous master, Lord Bruno (Offerman), whom he cuckolded. Father Tommasso (Reilly), knowing nothing of his background but needing a gardener to replace the one Fernanda scared away, tells him to pretend to be a deaf-mute, which, he feels, will placate the nuns. It doesn't. Instead, they take turns seducing him.

The big reveal in the third act is that Fernanda and her friend Marta (Kirke) are part of a coven of witches that meet regularly in the woods. Oh, and that the Father is getting it on with Sister Marea (Molly Shannon).

We get comeuppance from the Bishop (Armisen), but that’s about it. As for the confusing title? Apparently the last word is supposed to begin with a “w.” Hilarious. 

According to IMDb, writer-director Jeff Baena based his movie on Pasolini’s “The Decameron” (1971), but he didn't do much actual writing—just an outline. The cast improvised the dialogue. It shows.
