I'm looking for the name a movie that came out in the late 70's early 80's-I think. It is a true story of a group of children and their teacher that was taken hostage by a group of men in halloween mask's. They were taken out of the one-room school house and into the hills. The children and the teacher decided to kill their captures to escape. They were able to lure them in and kill them. The end of the story shows the kids back in the school with what appears to be human organs in the science corner of the classroom. This is suppose to be a true story. Please let me know if anyone knows the name of this movie. It is not an american film. THANK YOU!!!
