I watched this movie around 2014 on cable. I don’t remember many scenes but just the general plot and the ending. I’m desperate to find the title!

Plot: Four college girls come together to find the real identity of a masked serial rapist who has been attacking women on the woods inside the campus by tying them to a tree and then sexually abusing them.

One of the girls (red hair) was attacked by the rapist and she provides some details that helps them figure out his identity.

SPOILER – ENDING: Eventually they find out the rapist was the university’s librarian and manage to catch him.

Other details about the movie:

• Probably filmed in the late 00s to early 10s
• A European film, and judging from the language and culture most likely somewhere in Northern Europe or maybe even the Netherlands or Belgium??
