Evil Has a New Home

Ted Morgan doesn’t believe in ghosts, demons, or anything that can’t be explained. A loving but rational man, he wants nothing more than to make his 7-year-old daughter Emily happy. So when he stumbles across a beautiful antique doll in an old curiosity shop, he buys it as a gift.Emily is enchanted. The doll becomes her constant companion. But her behavior soon changes—erratic, distant, sometimes violent. At first, Ted and his wife Lori write it off as stress, imagination, or just growing pains. But the tension in the home grows unbearable. Doors slam on their own. Objects vanish. Whispers echo from empty rooms.Lori begins to suspect something is deeply wrong with the doll. Ted refuses to believe it—until the night he finds Emily sleepwalking, whispering in a guttural voice that isn’t hers.As the darkness spreads through their home, the family teeters on the brink. Ted’s refusal to accept the supernatural truth threatens to doom them all. To save his daughter, he must face a terrifying reality—and a demonic force that feeds on denial.

Logline

A well-meaning father buys a vintage doll for his young daughter’s—only to unleash an ancient demonic force. As his daughter’s behaviour grows more disturbing, he must confront a nightmare he refuses to believe is real… until it’s nearly too late.

Main Characters

Ted Morgan – A logical, down-to-earth father whose deep skepticism blinds him to the supernatural horror invading his home. His journey is one from denial to desperate belief.

Lori Morgan – Emily’s mother. Sensitive and intuitive, Lori is the first to sense the danger—but struggles to convince Ted that their family is under threat from something truly evil.

Emily Morgan – A sweet, imaginative 7-year-old girl. Her innocent bond with the doll turns into a disturbing connection, making her the perfect host for something far more sinister.

The Doll – Antique. Porcelain. Perfectly preserved. But it houses something ancient and infernal—an entity that feeds on innocence, fear, and disbelief.
