Around a newly built HLM stretch wasteland and brownfield providing refuge to young people fleeing the unfathomable tedium of family life in the Paris suburbs.
They share their secrets, the products of their thefts, submit to strict rituals.
The sanctity of their revolt is highlighted by the initiation by jumping blindfolded and blood rite of passage.
But the gang threatens increasingly sliding into serious crime, which is condemned by Dan and Lucky, a big brawler boy but who begins to consider an orderly life.
Lucky, on the run, and Dan discover a mutual romantic inclination, while Babar, cruelly mistreated and humiliated, commits suicide.
