On Thanksgiving night, 1983, a massive hurricane traps the eccentric Pascal family inside their sprawling Virginia mansion. Into this volatile atmosphere steps Anthony, who brings his naïve, wholesome fiancée, Lesly, home to meet his wildly
dysfunctional family. Waiting inside is his twin sister, the unstable and fiercely dominant "Jackie-O"—named for her obsession with Jacqueline Kennedy—alongside their passive brother, Brian, and their sharply detached,
alcoholic mother, Mrs. Pascal.From the moment Lesly arrives, the household’s bizarre dynamics and incestuous undertones are glaringly apparent. Jackie-O, who shares an uncomfortably intense, symbiotic bond with Anthony, views Lesly as a threat to her absolute dominion over her twin. Jackie-O’s primary motivation is to preserve her romanticized, delusional family unit, rooted in the tragic mythology of the Kennedy assassination. She quickly engineers a plan to sabotage the upcoming wedding, fueled by a jealous rage masked as eccentric charm.As the storm rages outside, tensions inside the house escalate rapidly. During dinner, the family’s dark secrets begin to surface. It is revealed that Jackie-O and Anthony once engaged in a deeply intimate relationship that crossed romantic and physical boundaries. Jackie-O demands that Anthony reenact the fateful day in Dallas, pulling him into her twisted psychological web. She gifts Lesly a replica of the infamous pink Chanel suit worn by Jackie Kennedy during the assassination, manipulating her into playing the role of the doomed President John F. Kennedy.Lesly, initially oblivious, slowly realizes the profound danger of the household. When she attempts to assert herself and claims Anthony for her own, the family's fragile stability shatters completely. Jackie-O's obsession turns violently theatrical. Armed with a prop gun, she reenacts the assassination, pushing the psychodrama to a terrifying peak. Anthony, torn between his toxic loyalty to his twin and his future with Lesly, is paralyzed by guilt and emotional enmeshment.The climax forces a reckoning when Anthony finally attempts to break free from Jackie-O's psychological grip, realizing that staying in the house means spiritual death. Lesly, shaken to her core but resolute, demands they leave immediately. As the storm finally clears and dawn breaks, Anthony makes a definitive choice to walk away from his family, abandoning the suffocating nostalgia of the house. Jackie-O is left behind in the wreckage of her own delusions, clutching her memories as the fragile illusion of the Pascal dynasty officially crumbles into the morning light.
