Le Pharmacien de garde (The Pharmacist)

Yan Lazarrec seems to be a normal man. He is a pharmacist who cares about the environment, soothes mankind with his potions and fights to protect the earth against the polluters who abuse it. Lazarrec is full of good intentions but, as one knows, the road to hell is paved with gold and it is precisely there, in hell, that the pharmacist spends most of his time because he has gone insane. In the shadow of his laboratory, he creates poisons to kill the polluters. The eco-warrior, the devoted pharmacist has secretly become a serial killer. And the irony of it all is that Francois Barrier, the cop in charge of the case, is also an environmentalist. The difference is that he goes about it with protests and demonstrations.
