Scottish archaelogist Angus Flint discovers an odd skull amid the ruins of a
convent which he is excavating. As people begin disappearing and acting
strangely over the next day or two, the skull is stolen from Angus' room, and
the watch of a missing person is found in a cavern which was the legendary home
of the D'Ampton worm. Angus and James discover that there was an ancient cult
which worshiped the worm as a god, and theorize that the creature somehow
survived its "destruction", but was trapped inside the cavern.
