The new movie Us, Jordan Peele's follow-up to Get Out, is a horror movie.
It starts with a black family on vacation. They go to the beach; dad buys a boat. Then things start getting creepy.
One night, another family dressed in red jumpsuits shows up in front of the house. And each member of this new family — mom, dad, sister, brother — is an identical copy of the family inside. They're doppelgangers.
