Nana has just been left by Mathieu. She goes looking for another man on social media and dating sites, hoping to find the worst. Nana's thwarted desires and loves come and go to the rhythm of clicks as to the rhythm of the tides.

A village in the distance, by the sea, where the Internet has arrived. "Mathieu started it" declared Nana in the prologue. Mathieu's "declaration" turns out to be as violent as it is naive. Nana goes to war: she decides not to cry, not to discuss, but to wage a war by going even further than her man in seduction on the networks, by seeking the worst. His war sows discord in the group of seaside girls and guys. Nana and her gang's thwarted desires and loves come and go to the rhythm of clicks as to the rhythm of the tides, in situations as unrealistic and eccentric as they are real and contemporary.
