Having only had one lover in her life-her ex-husband-Candice is hesitant to go to bed with her handsome neighbor, Hervé. Soon enough she's distracted from her dilemma by a new case, when a badly damaged body is found in a dump. Candice recognizes the victim as an occasional prostitute, and she deploys her unique assets to gain access to a "special" party.

The kids are happy to have their father, Laurent, back home, but Candice is far from thrilled. Meanwhile, she has work to do, as a woman in her 40s is found dead in her car. Candice notes the scent of a plant-based poison and learns the woman was an aficionada of natural medicines. As she calls upon her knowledge of herbal remedies to help solve the case, she also learns Laurent's true intentions.
