Felicie and Charles have a whirlwind holiday romance. Due to a mix-up on addresses they lose contact, and five years later at Christmas-time Felicie is living with her mother in a cold Paris with a daughter as a reminder of that long-ago summer. For male companionship she oscillates between hairdresser Maxence and the intellectual Loic, but seems unable to commit to either as the memory of Charles and what might have been hangs over everything.
