I am trying to remember the name of a film I saw where people have to abandon their own personality and free will to adapt to the standard of a community, similar in theme to "The Stepford wives". The unadapted character is a boy (I forgot the name of the film) who ends up killed with parental approval. Another detail of the film that somehow stuck with me is that in the end they plant a tree on the grave, never saying it is a grave, among other similar trees.
I think I saw it on DVD. I would also like to know whether it exists as a novel.
