Annie lives in harmony with her husband Laurent and her children: the sensitive elders Maximilien and César; the younger Antoine whom Poupi, never-complaining teen, helps raising him. But a positive pregnancy test will disturb the harmony.
A couple since high school, Charlotte and Adam have just had their first child. But they're not happy, and habits are gradually replacing enthusiasm, to the point of driving them apart... Hoping to recapture the momentum of their early days, they decide to become guinea pigs in a revolutionary treatment designed to strengthen their bond and desire.
Laurent is a thirty year old dreamer. The day he gets dumped by his girlfriend, he has to go back to his parents and discovers he has testicle cancer. His whole vision of life and priorities are then going to change.
