Jean-Gabriel intends to spend Christmas in the mountains quietly with his family. Many unforeseen events occur, but Jean-Gabriel will do everything to overcome them...

When 43-year-old hairdresser Suze Trappet finds out that she's seriously ill, she decides to go looking for a child she was forced to abandon when she was only 15. On her madcap bureaucratic quest she crosses paths with JB, a 50-year-old man in the middle of a burnout, and Mr. Blin, a blind archivist prone to overenthusiasm. The unlikely trio set off on a hilarious and poignant helterskelter journey across the city in search of Suze's long-lost child.
