The story unfolds with Belinda (Brandy Norwood), an anthropology professor, who faces considerable challenges as she lectures to a class filled with indifferent students. Pregnant with her second child, she grapples with the emotional weight of her firstborn son, Wallace, whose heartbreaking stillbirth continues to haunt her and her husband, Norman (Andrew Burnap). After a distressing ultrasound appointment, the couple's grief resurfaces when Norman receives a surprising call from his estranged stepmother, Solange (Kathryn Hunter), announcing the imminent passing of his father. Yet, old wounds run deep; Norman's memories of Solange are tainted with tales of emotional and spiritual turmoil inflicted during his upbringing, leading him to decline the opportunity to reconcile.
As the days pass, the pressures mount; Belinda, feeling underappreciated and sidelined in her academic role, decides to quit her job. Returning home, she learns of her father-in-law's death, and the couple attends the funeral where the dynamics shift dramatically. Solange, who shares a complicated history with both, makes her entrance, struggling to navigate with the aid of canes. It is here that their late family member's last wish is disclosed — that Norman and Belinda take Solange into their home for her remaining days. It's a deal laced with a bitter irony, as Solange promises to bequeath her possessions to the young couple upon her death.
After much internal conflict, particularly concerning their precarious financial situation, Belinda reluctantly agrees to Solange moving in. However, the transition proves to be anything but smooth. The vibrant front room, initially intended as a nursery for their baby, transforms into Solange's new domain. Upon discovering Solange’s Daughters of the Confederacy certificate, Belinda realizes the foundations of their living arrangement are overshadowed by deep-seated prejudices and an unsettling atmosphere. Throughout the evening meals, Solange's barbed remarks about Belinda's cooking and her disapproval of the baby's name — Fern — heighten the tension. Solange's suggestion to rename the child Laurie, after Belinda’s late father, further complicates the situation.
Days blur into a disturbing routine filled with unsettling incidents; Solange's bouts of incoherence, religious fervor, and errant behavior consume Belinda's life. During one particularly intense night, Solange's fervent prayers appear to trigger Belinda into labor, leading to the arrival of their daughter, now named Laurie. Tragically, post-birth, Belinda returns only to find a home filled with Solange’s decor and remnants of Norman's father. The subsequent prayer meeting ignites Belinda’s frustration, leading her to expel her friends who were praying fervently over her and her newborn.
The real challenges solidify in the aftermath of Solange’s insensitivity during dinner, where microaggressions surface, resulting in an explosive confrontation. Calling Solange out for her racism leads to an altercation that ends with Belinda pushing Solange down in frustration. As their tumultuous relationship spirals, Belinda witnesses Solange's manipulative nature first-hand, as she pretends to incapacitate herself, forcing Belinda into further emotional turmoil.
Continued confrontations between Belinda and Solange escalate when Pastor Lewis (Neal Huff) appears with revelations about Solange’s financial maneuvers, such as paying the mortgage without consent. A shift in power dynamics occurs when Belinda reacts in anger, pouring water over Solange. Yet the most shocking moment comes when Belinda wakes to find marks on Laurie's arm, exposing Solange's disturbing behavior as she becomes a threat rather than a caregiver.
As tension comes to a head with Norman standing up to Solange after the bite incident, the fraught atmosphere reaches a chilling climax. Norman’s confrontation ends abruptly with Solange's chaotic pleas for death echoing into the night. When dawn breaks, solace appears as Belinda discovers Laurie successfully latching, only to find Solange lifeless in her room shortly thereafter. Solange's cremation occurs with a strangely placid Belinda observing, contemplating the many shadows cast by their relationship.
The story reaches a poignant conclusion years later as Belinda prepares for a move into a new home while pregnant with twins. On her way to a job interview, she exuberantly sings "No Regrets" by Edith Piaf, exuding a sense of liberation. During the interview, when prompted about her past experiences, Belinda confidently declares she has "never felt better in her entire life." A haunting flashback reveals the depths of her desperation — she had smothered Solange, a revelation that culminates the film in a strikingly unsettling manner. As the screen fades to black, Belinda's smile echoes a peculiar mix of relief and buried secrets, sealing the film’s chilling exploration of trauma, family, and the lengths one will go to find peace.
