Uh-oh, some nuns have been naughty! Basically, this is Monty Python does Boccaccio's "Decameron." It's pretty silly and juvenile, but it's fun and the cast is great. Aubrey Plaza, Alison Brie, Dave Franco, Nick Offerman, John C. Reilly, Molly Shannon, Adam Pally, one half of Garfunkel & Oates, and the annoying British woman from "Girls" star. Jeff Baena, who is Plaza's boyfriend, wrote and directed.
