Garth is a guard at the Tower of London, but a tourist doubts his spooky tale. Together, they climb the tower to examine the old and darkened room. Garth points out the chapel where the headless dead were buried, and the flagstones that double as their tombstones. When the tourist is allowed to play the chapel organ, a ghostly voice is heard chanting in Latin. Has Mr Holman become a believer?
Left alone, Holman gets sleepy, but wakes in a chapel that seems the same, yet different. Is it actually happening? Do the dead actually rise up to stretch their bones? Holman learns that if he doesn’t join the procession of the dead, that he may not return from his experience.
Though he is let go, Holman tries to explain to his wife about his supernatural experience, and that he is commanded to return for a second night. Will he return? Has his skepticism crept back into his head? Was it all just a dream? What will happpen if he tries to flee from his appointment at the chapel?
