Okay, so I saw this movie (I think) on TV when I was younger, very possibly 10 or more years ago. I don’t remember if it was English or not, it’s very possible it was a Swedish movie since I live in Finland. I don’t remember exact details, but here’s some scenes I remember:
There was a group of boys, teenagers probably, not adults for sure. They were the main characters.
There was a boy who was hiding from someone, he hid in the attic of someone’s house. Later in the movie he got handed a fake ID.
There was a scene where two girls were playing something outside, possibly tennis, and some guy came, chased one of the girls and force-fed her grass.
There was a scene in the movie where the group of boys killed the hiding boy (I’m not too sure what exactly happened in this scene), and then they burned his corpse in a fire. One of the boys was holding a bloody shovel.
That’s all I can remember, the movie at the time seemed old-ish, possibly made in the 80’s or early 90’s.
