I watched a great horror movie when I was younger, unfortunately I can't remember the name of it! It's about a girl who goes to summer camp and she's the quiet, unpopular chick. She starts killing off the campers that were mean to her. I remember the ending best: one blond guy is nice to her but she kills him anyway... in the end scene she's sitting by the water naked next to his body. when the campers find her she rolls the guy's head away from his body. i've been going crazy trying to find out what movie it was, and so far no one else can figure it out either. If anyone has seen this movie or knows what i'm talking about PLEASE let me know. The movie had to be late 70's to 80's.
