I remember watching a movie a few years ago, but I can't find it anywhere. I think it was Scandinavian, but I didn't recognise the language (not German, Dutch, English or any Roman language) It was about a teenage girl who moved to a rural area with her parents. They tell her she isn't allowed to go to the nearby mansion or its courtyard, but one day she does anyhow. There, she meets another, older girl who seems to own the place. They start talking, get inside and have sex. Most of the movie follows the story of the fresh couple and the way their relationship evolves. Frequently they tell eachother that if they dumped the other, they would kill them (and I also think it was proven the older was a bad influence). Eventually the parents of the older girl get back from their holiday, and they tell their daughter she has to go to a boarding school, unavoidably also saying goodbye to her girlfriend. This prompts her to meet up with the younger girl at a pond, and break up with her, just to promptly get pushed into the water, nearly drowning her.
Now here are a few details I am not sure about: I think the younger girl was around 15 with long, blond hair. The older girl, whose age I guess is around 18, had short red/brown hair. Most of the movie was set either on the hills and fields, or in a room of the mansion (most noteably the bedroom). The parents of both girls make short appearances in the film, but I don't recall any other characters. There was a short scene of the younger girl riding her bike over the freeway through the heavy rain though, and it migh've been right before she tresspassed on the mansion courtyard.
Anyone who could help me with the title would be SUCH a help. Not knowing has been driving me crazy. Thanks to all anyways.
