While the couple Zoé and Ben are staying in a hotel in Paris, their sleep is disturbed by a rustling noise from the next room. At first they think it’s a mouse that’s up to mischief in a paper bag. But they quickly notice that the paper bag itself is making noises and seems to be breathing. Ben tries to be logical about it, but Zoé’s emotions suggest that the bag found its way into her life for a very different reason.
