The mysterious stranger who knocks on the McCabe family's door is a charming and enigmatic man named Norman. Initially, the McCabes, consisting of married couple Adam and Sarah and their young daughter Emma, are hesitant to invite Norman into their home. However, Norman's charismatic demeanor and convincing story about needing help after a car accident convinces them to let him in.
As the weekend progresses, strange events begin to unfold. The family starts witnessing unexplainable and supernatural occurrences within their house. Objects move on their own, eerie noises echo through the hallways, and Emma experiences terrifying nightmares.
Adam and Sarah slowly realize that Norman is not who he claims to be. They investigate Norman's background and discover a dark past involving a series of mysterious deaths that have followed him throughout his life. Fearing for their daughter's safety, and no longer able to explain away the paranormal happenings, Adam and Sarah confront Norman.
It is revealed that Norman is a malevolent spirit who has manifested himself in human form to torment the family. He seeks revenge for a perceived wrong committed against him in the past. As the family fights to protect themselves and their home from Norman's wrath, they uncover a hidden secret from their own past that is connected to him.
Desperate, the McCabes turn to a local paranormal investigator for help. Together, they attempt to unravel the truth behind Norman's identity and find a way to banish him from their lives. As they delve deeper into the mysteries and confrontations, the supernatural encounters intensify, putting their lives at risk.
With their determination and resilience, the family finally uncovers the key to defeating Norman. Through a combination of bravery, intuition, and quick thinking, they manage to trap him and restore peace to their home.
In the end, the McCabes learn that their encounter with Norman was not a random event, but a lesson about the importance of facing their own demons and the power of family unity and love in overcoming adversity. They emerge from their ordeal stronger and more connected than ever before, ready to face any future challenges that may come their way.
