Cécile and Alain have been living together for twenty years. He runs a small hi-tech engineering company in Grenoble that is doing well – extremely well – and although she has no need to work, Cécile continues to teach at the local high school.
They are a wonderful, indestructible, model couple, to the great chagrin of their doctor friend, Georges, who is not insensitive to Cécile's charms.
Cécile has always been anxious by nature, but this time she is sure that Alain is hiding something from her.
He’s right to keep what’s troubling him hidden. If Cécile knew the truth she’d be distraught. Alain thinks he’s going to die. In a few days, Georges is going to operate just to make sure.
