A police investigator specializes in busting as many narcotics dealers as he can, but aside from the sad fact that drugs seem to have permanently permeated society, his sincere efforts are often undermined by his own department superiors. Both aspects are very well dramatized. As well, he faces the problem in a more personal way because of his ambiguous relationship with a heroin addict prostitute. At one point his best street informant is exposed by one of the officers in his own police unit, who declares that "you can always find another one". Laying the groundwork, going from stakeout to stakeout and from slum to slum, the film has a gritty authenticity and the main character played by Didier Bezace makes a unique cop who actually believes in what he's doing.
