简介：　　Annie, whose married life with Laurent is a picture of harmony. Her two young kids, Maximilien and César, are brilliant and sensitive boys, and Poupi, her teenage daughter, supports her willingly and patiently in bringing up Milo, her latest arrival. It’s a perfect family that Annie controls with a firm but loving hand. Yet one morning during an apparently uneventful weekend, the discovery of a "forgotten" positive pregnancy test left lying around in the bathroom shatters this harmony into a thousand pieces. Who does the test belong to? As she embarks on a crazy investigation to find out the owner of this object, and despite her best efforts to save face, Annie will see all of her certainties turned on their heads, and the pack of cards that life has dealt her entirely reshuffled.
