Here is the summary from IMDB:
In a dystopian near future, single people, according to the laws of The City, are taken to The Hotel, where they are obliged to find a romantic partner in forty-five days or are transformed into animals and sent off into The Woods.
It was certainly a very original movie. Dark and funny in parts.
Will not be for everyone. But if you like Spike Jonze movies, this could be right for you.
