A family of four—the parents Phillip Dennis Weaver and Laura Valerie Harper, their son Kevin Oliver Robins, and daughter Mary Robin Ignico—move to a new home with Grandma Bernice Ruth Gordon, mourning the loss of their sister Jennifer Kristin Cumming. They hope this change will help them begin anew and put Jennifer’s tragedy behind them.
Seeking to start fresh, the family believes the house could be a place to heal and build a new life together. But soon after settling in, Mary hears a voice that seems to come from beneath the bed, calling her name as if Jennifer were still nearby. When Mary investigates, she discovers that Jennifer has returned as a ghost and begins to appear to her repeatedly, revealing a chilling wish to kill the entire family except for Mary.
This devastating revelation unleashes a sequence of twisted fates: Kevin’s iguana somehow ends up in Grandma Bernice’s bed, triggering a fatal heart attack for the elderly woman; Kevin’s attempt to retrieve a Frisbee from the roof ends in a deadly fall; and Phillip, while bathing, listens to a radio that ends up electrocuting him, leaving Laura to scramble to safety, though she sustains an arm injury in the process. Believing Mary to be the killer, the authorities place her in a mental institution as she grapples with the horror of what she may have done.
A pivotal flashback reveals the siblings’ hidden tensions: Kevin, feeling overshadowed by Jennifer, persuades Mary to join in a prank by tying Jennifer’s shoelaces together. The prank spirals out of control when a van collides with the family car, and while everyone except Jennifer manages to escape, she screams for help as Mary races to warn their father. But Phillip is unable to rescue her before the car bursts into flames, leaving Jennifer to perish in the wreck.
In the present, Mary insists that she is actually Jennifer, as the deceased sister possesses her living self, blurring the line between victim and perpetrator. Later, Laura lies in bed when Jennifer’s ghost appears at the foot of the bed and greets her with a chilling greeting: > “Hi, Mommy.” The film closes with Laura’s terrified screams echoing through the room, leaving a house full of unanswered questions and lingering dread.

In the wake of a heartbreaking car accident, a family of four seeks fresh beginnings by moving into a secluded house that promises space for healing. The parents, Phillip and Laura, bring their teenage son Kevin and daughter Mary along with a stoic grandmother, Grandma Bernice, hoping the new setting will soften the ache left by the loss of the younger sister, Jennifer. The home, however, immediately feels less like a sanctuary and more like a quiet stage for lingering shadows, its rooms whispering with an uneasy stillness that seems to echo the family’s unspoken grief.
Mary is the first to sense that something is amiss, convinced that a presence lingers beneath her bed—a sensation that evolves into vivid, unsettling visions of Jennifer herself. These apparitions blur the line between memory and reality, turning ordinary corners of the house into sources of both curiosity and dread. The atmosphere is thick with a slow‑burning tension, where the familiar comforts of home are constantly undercut by a subtle, otherworldly pulse that hints at unseen forces at work.
The adults grapple with their own ways of coping: Phillip tries to maintain a veneer of normalcy, while Laura balances maternal protectiveness with the need to let her children process the tragedy. Kevin, caught between teenage rebellion and family responsibility, drifts through the house, his interactions with the lingering sorrow adding another layer to the household’s fragile equilibrium. Grandma Bernice, with her quiet resilience, offers a grounding presence that contrasts sharply with the growing unease.
Together, the family inhabits a space where every hallway, every creak, and every fleeting glimpse of the past feels charged with mystery. The house becomes a character in its own right, wrapping its occupants in an ever‑tightening veil of suspense that invites questions about what truly haunts the night and whether the line between the living and the dead can ever be fully discerned.
