Plot Synopsis

Seven-year-old Isabela "Bela" Martin struggles to adjust to a new school while her parents' marriage becomes increasingly strained. Her mother, Ursula, is absorbed in her corporate career, leaving much of Bela's care to her unemployed husband, Russell "Russ" Martin. During this period, Bela begins seeing a supernatural figure resembling Ursula. Calling itself "Other Mommy," the entity repeatedly asks Bela to let it into her heart.

Other Mommy's appearances grow increasingly disturbing as it follows Bela outside her bedroom, assumes different forms, and manipulates its surroundings. During a family party, the entity seemingly causes the guests to vanish before lifting Bela toward the ceiling and attempting to enter her body. Bela fights it off and falls back into the crowded room. Alarmed by the incident, Ursula and Russ take her to stay with Ursula's friend Frank.

While staying at Frank's house, Bela discovers Ursula's contact lens case, prompting Russ to suspect that the two are having an affair. Other Mommy exploits the resulting tension, manipulating Bela into wishing Frank would disappear from their lives.

The entity then murders Frank in front of the family, remaining unharmed despite his attempts to shoot it. They escape to a restaurant at a shopping mall, where Other Mommy attacks again, transporting Bela from the children's play area to her bedroom and then to a lake below a hilltop mansion. There, it claims that Ursula never wanted Bela to be born before returning her to the family car.

Desperate for help, Ursula and Russ bring Bela to her grandmother Ruth, who has experience dealing with supernatural phenomena. Ruth takes them in and hires a team of paranormal investigators, who identify Other Mommy as a trickster demon attempting to take physical form by possessing Bela.

However, the entity cannot enter her without her consent. Ruth also explains to Bela that suffering is an inevitable part of life. When the investigators attempt to summon Other Mommy through a séance, they discover that their methods are ineffective against it. The demon kills them, forcing the family to flee once more.

No longer willing to run, the family returns home to confront Other Mommy. Their attempts to fight it fail, and they retreat to the basement. There, Ursula admits that she initially did not want to have Bela, fearing that motherhood would cost her independence. She nevertheless assures Bela that she loves her and wants to be her mother. Ursula also reveals that Russ is not Bela's biological father, explaining that she was married to another man when she began an affair with Russ.

Although Ursula's confession appears to weaken Other Mommy, the revelations devastate Bela. She retreats to her bedroom and begs the entity to enter her heart. Other Mommy appears and promises to protect her from ever experiencing pain again. Remembering Ruth's warning that suffering is an unavoidable part of life, Bela rejects the offer and attacks the demon, repeatedly refusing to grant it permission until she defeats it.

Months later, Bela and her parents appear to have settled into a happier life, decorating their home with Christmas lights. However, Bela begins noticing signs that Ursula's unhappiness is resurfacing.
