The group of companions consists of a young couple, a skeptical journalist, a psychic medium, and a paranormal investigator. They are initially drawn to the deserted house after hearing stories from locals about strange occurrences and unexplained deaths that have taken place there.
As they explore the house, they begin to experience supernatural phenomena such as sudden drops in temperature, disembodied voices, and objects moving on their own. The psychic medium senses a malevolent presence in the house and warns the group to leave, but they are determined to uncover the truth behind the house's dark history.
As they split up to investigate different areas of the house, they are picked off one by one by the vengeful spirits that haunt the house. The severed heads of previous victims appear, blood drips from the walls, and demonic clown dolls come to life, terrorizing the group.
The group soon realizes that the house is a portal to another dimension, where the souls of those who died within its walls are trapped and seeking vengeance on anyone who enters. They must band together and confront the evil entity controlling the house in order to escape with their lives.
In a climactic showdown, the group battles the malevolent spirit and manages to banish it back to the realm of the dead. They flee the house, barely escaping with their lives, but haunted by the horrors they witnessed within its walls.
Ghosthouse is a terrifying tale of supernatural revenge and the consequences of meddling with forces beyond our understanding. It serves as a cautionary reminder that some places are best left undisturbed, lest they unleash their deadly past upon unsuspecting visitors.
