I really cant remember much but I've watched it when I was a kid.
It's about an angel (or so I think) and she spent a day with a guy and then he got drunk and then he was brought in by the angel in a hotel
The front desk asked the girl (angel) if she has extra baggage and he pointed at the drunk guy on the floor and he was brought in the room.
I think it was a french movie or something. Then the boy wont believe that she was an angel until she flew up in the air and showed her wings,
