Poltergeist, which is currently available to stream on HBO Max, follows an ordinary suburban family who begin to experience strange things in their home. Furniture and toys move on their own, a glass of milk shatters out of nowhere, and the youngest child in the family, five-year-old Carol Anne (Heather O'Rourke), begins to communicate with beings through the television. At first these events are dismissed, but during a thunderstorm one night, a tree outside the windows of the kids’ room crashes in and snatches the boy. Then, a portal opens in their closet, sucking Carol Anne into another dimension. With help from some paranormal investigators, the family tries everything to bring her back.
