Plot.
University student Audrey Camuzet works in Paris as a hotel maid where Gary Newman, an American businessman from Silicon Valley, is staying. The night after his meeting, Gary has difficulty sleeping and suffers a panic attack. When morning arrives, he stays in his room, deliberately misses his flight to Dubai where he had further business. He decides to quit his job, divorce his wife Elizabeth, leave his family and remain in the hotel indefinitely.
Audrey tidies Gary's room after initially being surprised to find that he had not yet departed and discovers he was supposed to already be in Dubai. When the hotel experiences an electrical blackout, she goes to the roof to investigate and transforms into a sparrow. She glides down to the ground, overhears other people's conversations, practices her new found flying abilities and peeps into various hotel rooms. After checking on Gary, she returns to the hotel roof and finds herself unable to return to her human form.
That night, she follows coworker Simon in his car to a park where he sleeps. After escaping attacks by a cat and an owl, she returns to the hotel roof. In the morning, she awakens in her original form once again. Later, Audrey literally bumps into Gary as he checks out of the hotel. They share an elevator ride and a conversation.
