This is absolutely the worst waste of time of my movie-watching life. I wanted to watch a good revenge-horror film. But I wish I could rewind my life & not watch this film. To save others from similar fate, I will summarize the movie's ending.
***** Spoiler below ***
The incompetent couple capture and torture the wrong guy (who looks very different from their son's real killer) despite the fact that the killer was tried and convicted at a trial that the couple attended. So despite the fact that everyone, including the audience, knows that they have the wrong guy, the oblivious ex-parents brutally torture him. This is such unbelievably incompetence that you wonder if they are the actual parents of the murdered child or crazy idiots whose child is at a summer camp but believes that the murdered child is theirs. The real killer meanwhile escapes but is recaptured by the police.
