When Zoé and Ben, a married couple, spend the night in a hotel in the city of Paris, their sleep is disturbed by a noise coming from the next room. At first, they think it's a mouse messing around inside a paper bag in the trash can. However, they suddenly notice that the paper bag itself is making noises and seems to be breathing. Ben attempts to approach the matter logically, but Zoe's emotional reaction indicates that the bag has found its way into their lives for a deeper reason.
