Claude is a young teenage girl tormented by murderous desires. She lives on her father's farm with her younger brother Michel and her cousin Sylvie, a city girl who comes to spend her holidays in the country. Then comes Pierre, a young student hired as a farm boy. An amateur photographer, he watches, like a vulture, for the two female prey. Claude is sensitive to this clumsy man's familiarities. Will she let herself be guided by his impulses?
