Haunted by an unexplainable and unresolved trauma from her past and compounded by a string of eerie coincidences, Adelaide feels her paranoia elevate to high-alert as she grows increasingly certain that something bad is going to befall her family.
After spending a tense beach day with their friends, the Tylers (Emmy winner Elisabeth Moss, Tim Heidecker, Cali Sheldon, Noelle Sheldon), Adelaide and her family return to their vacation home. When darkness falls, the Wilsons discover the silhouette of four figures holding hands as they stand in the driveway. Us pits an endearing American family against a terrifying and uncanny opponent: doppelgangers of themselves.
There's an instant flirtation, though restrictions dictate that they must maintain a safe distance between them. As their connection intensifies, so does the temptation to throw the rules out the window and embrace that attraction. Further complicating matters is Will's potentially dangerous rebellion against his ongoing medical treatment. Stella gradually inspires Will to live life to the fullest, but can she ultimately save the person she loves when even a single touch is off limits?
