Doctor Who: Ghost Walk

This is a city of ghosts and no-one knows them better than Leanne. Twice a night she leads tourists to visit the most haunted sites - the Hanging Yard, the Witch Pool, the Screaming House, and, of course, the Catacombs.

Leanne's realised the ghosts of the city are real. Something's lurking in the Catacombs - an ancient force that has been growing in the darkness for centuries. Sabaoth is returning and they must be stopped before they devour the world. Leanne knows this, because a ghost told her.

A ghost called The Doctor.
