Chris Washington, a young African American photographer, and his girlfriend, Rose Armitage, a white woman, make their way up the Hudson River on a twilight drive, heading to Rose's family estate in the countryside. As they navigate the winding roads, Chris engages Rose in conversation about their weekend plans, trying to gauge her expectations. Rose seems hesitant to discuss the details, but assures Chris that her parents will be fine with their relationship. Upon arrival at the estate, Chris is greeted by Rose's family, who appear welcoming, yet slightly eccentric. The father, Dean Armitage, is an old-school psychoanalyst who is immediately taken with Chris, inquiring about his profession and displaying a forced interest. Chris's anxiety about visiting the predominantly white neighborhood is palpable, and he reads the family's behavior as overly accommodating, possibly a nervous response to Rose's interracial relationship. The initial tension is somewhat alleviated when Rose introduces Chris to her mother, Missy Armitage, who is equally fixated on Chris. Her mother's fixations on the boyfriend aspect of the situation makes him increasingly uneasy. Chris senses Rose's parents are using polite overtures to disarm him, while probably subconsciously wondering about Chris's possible "appropriateness" as a partner for their beloved daughter. Chris tries to be optimistic, finding humor in the situation and trying to connect with Rose and her family. The atmosphere becomes even more bizarre as the night wears on, with Rose's father and step-dad introducing Chris to the weekend's festivities, including white wines and conversation discussions centered around music. However as the evening progresses, and also through conversations over the weekend, Rose and Chris attend a dinner party. During this he unwittingly encounters a combination of suspicious and unrelatable white upper-class individual in the name of Logan King, Rod Williams, and Jeremy Armitage a household helper he had gotten suspicious on from the beginning. Although the Armitages go through the motions of inclusive behavior around him, they subtly conflate these tensions as mere social graces rather than racial prejudices. It becomes disturbingly apparent to Chris that this unidirectional behavior, devoid of equality or social connection, may be even indicating an ulterior motive. Just how far would Rose's parents go to rectify their concerns? Another evening's conversations take a twisted turn. Later, as the festivities continue into the early morning hours, Dean invites Chris to his study to deliver words of advice about their relationship. Upon agreeing to the discussion, Chris senses an unusual reluctance, getting close to leaving again; Chris heeds the sense that something really bad is quickly approaching. The sudden interaction raises unease as a scenario starts pouring out that's extremely macabre and despicable. This scenario gradually reveals itself before returning viewers: they practice a hybrid of cloning and brain transplant where the white elders gain from mentally enslaving and housing the African American children of many mixed birth where over time as they live through hundreds of black, they develop highly tolerant society as they continue accepting very aggressive yet very respectful family member who is a social fixture which over powers how long blacks can even live on in many specific human memories. Also another twist - just as Chris began to suspect that he had stumbled onto something sinister, he starts uncovering that Rod, whom he befriends at the party, was one of his hosts' patients - who had gotten away for the first time from their hypnotic treatment then ultimately he comes in the light - Rose is one of the many trapped souls.
