Hello guys, I`m looking for a movie I think 6-9 years old. Plot goes like this 3 or 4 friends (one is a girl) are bullied in school and seek to get some revenge on the bullies.With the help of 2 older students that have a large cabin/farmhouse surrounded by woods they trow a party and invite all students of their year to it, all except of the black guy who is nice with them. He comes anyways
They roofie the drinks, all pass out and they awake in chains. They start torturing students, I remember a scene where one of the bullies is tied to a chain and one of the guys stab his spine till the bully is crippled.
Does anyone remember this movie as well? I can`t seem to find anything on it...
