Haunted by a family tragedy, Dan begins to restore videotapes for a cryptic firm. Then he's startled to learn of his connection to their missing creator.

In the woods, Dan encounters the unexpected. In the tapes, Melody learns about the cult and makes contact during a shocking séance.

The past blurs into the present when Melody visits a forbidden floor in search of an inspired Anabelle. Music leads to lost souls — and revelations.

The Otherworld beckons. Melody circles back to the Visser, where a new device captures a sacrifice. So much depends on Dan's journey into the unknown.
