Summary You Should Have Left 2020
A former banker, his actress wife, and their spirited daughter book a vacation at an isolated modern home in the Welsh countryside where nothing is quite as it seems.
The stressed and jealous middle-aged banker Theo is married with the young actress Susanna and they have a six-year-old daughter, Ella. Theo is a hated man since he was accused of drowning his first wife, but he was considered not guilty by the justice. Out of the blue, they decide to travel on vacation to a huge, isolated house in the Welsh countryside to resolve the problems in their relationship. But soon they have nightmares and Theo believes something evil is hidden in the house.
Theo Conroy (Bacon) is a successful middle-aged man whose marriage to his much younger actress wife, Susanna (Seyfried), is shredding at the seams, frayed by her secretiveness, his jealousy, and the shadow of his past. In an effort to repair their relationship, Theo and Susanna book a vacation at a stunning, remote modern home in the Welsh countryside for themselves and their six-year-old daughter, Ella (Avery Essex). What at first seems like a perfect retreat distorts into a perfect nightmare when Theo's grasp on reality begins to unravel and he suspects that a sinister force within the house knows more than he or Susanna have revealed, even to each other.
