The hazy lazy days of late summer are perfect for a naughty-nun comedy! Jeff Baena’s film is adapted from parts of the 14th-century work The Decameron. But fear not: It stars a virtual convent of your favorite comic actors (Alison Brie, Aubrey Plaza, Kate Micucci, Molly Shannon, John C. Reilly, Dave Franco, Fred Armisen, Nick Offerman and more), and is an amusing piffle of a comedy of (sex) manners. The plot is as old as time – or at least as the 1300s — when life in a cloistered convent is disrupted after a hot young man seeks refuge there. (He’s on the run from the crime of being a sexy beast.) The young nuns compete to … um … counsel him, and profane screaming matches, a boozy late-night bitch fest, and a black-magic ritual ensue. The fun is in watching these actors — dressed up in an assortment of drab robes — play this silly farce with straight faces.
