Whats the name of this foreign crime thriller? Pls help! - MIGHT have the word "life" in the title

I saw this clip on FB and really want to watch the movie but I cannot find it anymore! :frowning: Basically it’s a story about a young boy in a town/village that maybe accidentally killed a girl and he hid her body? and covered up the accident and even joined search party to find her with the community…and thats all I know. It MIGHT have been in French, but not sure…? Can anyone help me?
