A Mediterranean scrubland. The relentless noise of crickets. In the distance a highway and the procession of lorries travelling through the countryside at top speed. Among the green oaks and thorn bushes the construction of a leisure Centre is nearing completion. On the other side, from the building workers' prefabs can be heard the happy chaos of children shouting, families getting together and Ramadan celebrations. Moving incessantly between the two, are Fabienne, daughter of the manageress of the Centre, and Latifa, daughter of one of the workers. Fabienne and Latifa are friends, they tell each other everything, or almost... When you are 16 there are secrets that you don't share, even with your best friend. Then, there are questions which one would love to be able to answer and mysteries one would love to understand... The Centre's opening day approaches. It is the day of Fabienne's 16th birthday. But why do her mother Anne and her uncle Tom seem to be so fearful of that day?

September, 1986. Alice and Martin are 17 years old. They come from provinces to Montesquieu high school in the capital. Like many youngs of their age, born in the 70s and nostalgic of a too comfortable childhood, they progress carefully in life. While Alice and Martin are finding their footing, demonstrations against the Devaquet law and the tragic death of Malik Oussekine are happening.

Loic and Sophie are siblings living with their mother in a block of flats. The impetuous, promiscuous Loic is a talented photographer about to make it to the big time, but being pulled back by loyalty to his best friend and ex-lover, both junkies. Sophie, a schoolgirl on holidays, is quietly undergoing a sexual awakening, observing from a distance Loic's milieu; she begins an affair with his business partner to Loic's quasi-incestuous disapproval. Loic is spotted by a prominent editor, but becomes increasingly unhinged, by his friend's violent struggles with dealers, by his lover's demands, by Sophie's 'betrayal', by his own 'demons'. Tragedy inevitably strikes.
