I watched this movie a couple of years ago on TV and I can't remember the name of it. What happens is I think a group of people go camping somewhere on an island then one of them gets killed by dogs I think they might have been german shepherds but I am not sure then I think maybe one or two of them get killed by bear traps. Then it turns out that the person that has been killing everyone is the father of a boy that they group of people killed earlier or something please help with the name of this movie.
