OK I saw this movie a few years back on TV, I don't know any of the actors or what year the movie was made. Its about a man that's son was kidnapped like 6 -10 years back. He assumes he is dead I think, at some point he is at a jail, he might have been a cop, I'm not sure, then I think he hears about a house, goes to this house, it has cages that people use to be in, and videos of children being tortured and molested, somehow the people got out, they are like animals because they were caged and tortured for so many years, then at the end he sees his son(I think its at a school) and he tries to talk to him and I think he hugs him, and then his son kills him.. it's a messed up movie I know.. I have been searching for it for like 3 days.. you WILL be my hero if you can name it.
