After the death of his parents, Pierre is forced to care for his younger sister Nathalie by committing petty crimes. In a recurring motif of Gérard Blain’s cinema, Pierre is taken under the wing of an older gay man, Hubert , who offers him work and financial security; but when Hubert makes advances to him, Pierre robs him and takes up with a group of radical leftists who are planning terrorist attacks. Without employment, Pierre loses Nathalie to child services and spirals into desperation, finally erupting in an act of horrific violence. An x-ray showing the largely undiagnosed sickness of its time, and a stern warning to ours.

Two teenage lovers are caught up in the thrill of forbidden love in this tragic romantic drama. Pierre (Jean-Pierre Andre) is a 16-year-old French lad who loves 14-year-old Djemila (Nadja Reski), the offspring of Algerian immigrants. Pierre's father is an Algerian war veteran who tolerates living with the immigrants at the low-income housing project as long as the two factions are separated. Djemila's older brother carries bitter hatred for the French over their invasion of Algeria. Both young lovers fall victim to the intolerance of their families when their relatives discover that the two are engaged in a passionate love affair.
