Martin is a guard at the Pyrenees National Park. He works in particular on the follow-up of the bears. But for months, there has been no trace of Cannellito, the last plantigrade with a little Pyrenean blood. Martin is more and more convinced: the hunters will have had the skin of the animal. So, when he comes across a photograph showing a young woman in front of the remains of a lion, hunting bow in hand, he is determined to find her and deliver her to public opinion. Even if he only knows her by her social network nickname: Leg Holas.
