My (2 discs) - Blu-ray + 4K Ultra HD

Adelaide Wilson returns to her childhood summer home on the Californian coast with her husband and two children for a holiday getaway. Haunted by a traumatic experience from her past, the seemingly composed and happy woman finds a series of seemingly innocent events triggering intense paranoia and a sense that their family idyll is about to end.
Her premonition becomes reality when, in the middle of the night, four strange figures appear in their driveway and soon attack the family. The terrifying nightmare is made even more horrifying by the fact that the attackers look exactly like the Wilsons. Except they're holding weapons. And they won't hesitate to use them.
