An excellent psychological thriller, available for free on Netflix. A married couple runs into an old high school friend, a “friend” who has a habit of dropping in on the wife while the husband is at work, and at other times, leaving a gift on the front porch. It gets weirder when he invites them over to his house for dinner, then gets a phone call and leaves them alone in a strange house.
After the “friend” returns, they have a big blowout. The next day their dog disappears. And it gets stranger. The surprises keep coming, and you’ll be surprised at how this one ends.
