A fresh rom-com in winter, a daring and hilarious fake date that fails to hide all the family's secrets.

Iris, 19, has been secretly in love with her best friend, Charles, since they were children. After six months in the United States, Charles returns to Bordeaux for the Christmas holidays. Iris is convinced that the distance will have made him realize that they are meant to be together. Unfortunately, Charles is not alone at the airport: he is accompanied by Jude, his new girlfriend. Iris' hopes are immediately dashed. So, before setting out with him, as she has every year, to celebrate Christmas in the Pyrenees with their respective families, Iris gets a crazy idea: what if she asked Alex, Charles's older brother, to pretend to be her boyfriend? And what if he agreed to play along?
