Chris, an African American photographer, reluctantly agrees to meet the family of his white girlfriend, Rose, unsure of how they will react to their interracial relationship. Upon arriving at her parents' secluded estate, he finds their over-accommodating behavior odd but chalks it up to awkward attempts to deal with their daughter's unexpected romance. As the weekend progresses, Chris meets Rose’s brother, whose aggressive behavior veers between sibling rivalry and outright menace. The presence of the family's overly polite black servants, Georgina and Walter, also strikes Chris as bizarre.

The visit coincides with an annual gathering hosted by Rose's parents, which brings a number of wealthy and prepossessing guests to the house. Chris's discomfort escalates as the guests’ questions and comments about race become increasingly intrusive and unsettling. His experiences persuade him to confide in his best friend, Rod, a TSA officer who provides a humorous yet grounded perspective. Meanwhile, Chris’s interactions with the other black individuals around the estate prompt suspicion, as they exhibit strange and alarming behavior, suggesting that something insidious lies beneath the veneer of this affluent community.
