A man dies mysteriously in his home. Unaware at first, he becomes a ghost, trapped in the house. As time passes, the truth unravels: his wife and her lover were involved in his death. He's not just bound by grief but by betrayal and unresolved purpose.
Years later, a new family moves in, and with them comes an ancient, sinister force that preys on the living. Though vengeful and broken, the ghost decides to protect the new family.
In doing so, he reveals his presence, confronts the dark force, and helps the family survive.
After the battle, a mysterious being (maybe a celestial figure, a spirit guide, or a member of a secret order) approaches him and offers him a second purpose: hunting supernatural entities that feed on humans - in exchange for freedom and a loyal hound spirit linked to his soul.
