Laura (Lily-Rose Depp), 17, is on a camping holiday in Dordogne with her aunt and cousins. She has a secret fascination for anything morbid, including suicide. That’s why it’s no surprise when, unlike the others, she’s not terrified by the supposed presence of a panther in the vicinity, but strangely attracted to it. The feline is potentially responsible for the disappearance of several people, including a young man Laura just met at the campground. She also meets Paul, an older author who writes thrillers, but when she breaks into his house, she finds strange things there.
