In the climax of the movie, the Bowen family faces a supernatural confrontation with the malevolent entities haunting their home. The family’s youngest daughter, Madison (Kennedi Clements), is trapped in the spectral realm, and her parents, Eric (Sam Rockwell) and Amy (Rosemarie DeWitt), desperately try to rescue her with the help of paranormal investigators.
In the resolution, the family discovers that the entities are using a portal through the closet to enter our world. The paranormal team attempts to rescue Madison by using a rope and harness to enter the other side. However, the plan goes awry, and Eric is pulled into the spectral realm.
In a climactic showdown, Amy and her son Griffin (Kyle Catlett) face off against the supernatural forces to save Madison. Amy dives into the portal, confronts the entities, and successfully retrieves Madison.
The film ends with the Bowen family escaping the haunted house as it implodes, and they move into a motel. However, the closing scene hints at the possibility of lingering supernatural activity, leaving the fate of the family somewhat uncertain.
In summary, “Poltergeist” concludes with the Bowen family overcoming the supernatural threat and rescuing Madison from the spectral realm. The film maintains the horror elements of the original while introducing some modern twists to the story.
