a boy sees his father shoot and kill his mother, later as an adult he revisits the house(he inherited it) and commits adultery there with a woman he picks up hitch hiking, it turns out the incubus that was, messing with his mother is now a succubus messing with him,  it also some how involves alternate reality, his grown children remember him as an absent dad, he remembers it all differently.

I seen the movie in2016 and had it saved on my DVR but lost it somehow
