I don’t remember if this was even the plot to the movie or not, but all I remember is that there’s a little boy who authorities fish out of a lake and when the mom goes to identify the body, she claims it isn’t him. It looks a lot like him but she says something isn’t right. They wouldn’t let her too close. I want to say that at some point she got ahold of the body and realized it was fake and that it was all a big cover up for something. Please help! I’ve tried to look it up with no luck.
