“The Back Room” is a beautifully shot and exquisitely performed film that tells the simple tale of a young shopkeeper (Vilem Cage) in Prague who discovers that he can make a lot more money renting out the storage room in the back of his shop for afternoon assignations to couples who can't find anyplace else to get it on, than he ever could by merely selling groceries. The models are gorgeous, the action sizzles, and there is enough foreskin to satisfy even the most demanding viewers. This is Eastern European sex play at its very best.
