Camille a mercurial César-winning actress has seen better times. Estranged from her husband she's with her children only every other weekend. It's her weekend but her agent has booked her to MC a Rotary club dinner in Vichy. She takes them with her and when her husband learns this he demands to pick them up at once. She bolts in a rented car to the seaside trying to improve her relations with the children especially the precocious and distant Vincent. He loves astronomy. A rare meteor shower is due in a few days so she suggests they go to a plateau in Spain hoping to see it. He agrees but the relationship remains difficult and her husband is on their trail.
