After years of despair, Layla is finally pregnant. But her joy shatters when the ultrasound shows nothing. Yet she can feel it kicking inside her.

A child's voice whispers in the dark: "Mama... open the door."

Everyone thinks she's losing her mind. Her husband, her doctors-they all see a woman broken by grief. But Layla knows the truth: this is no child. It's an ancient, hungry entity, born from a blood-soaked bargain. And it isn't growing in her womb... it's building itself there.

Therapy can't save her. Science can't explain it. To survive, she must delve into her family's dark past and trust the "superstitions" of old women who knew that some doors are better left unopened.
