A lethal cord of cause and appalling effect connects the Vermont hills and a haunted woman a thousand miles away. When a young woman in Alabama turns up in New England in an instant, Delta Green sends your Agents to learn how and why. Learning that her vanishing was the work of some strange and fearful gift is only the Agents' first step on a journey of revelations and terrible awakenings. To save her and others, they must follow a trail of horror into night-black woods and vertiginous hills where silence drowns all hope.

Presence is a complete scenario for Delta Green, the role-playing game of Lovecraftian horror and conspiracy.
