As for the official plot synopsis of episode 12, Spoilers Guide notes, "The Koenigs are back, and the fate of the world is in their hands. Agents Sam and Billy Koenig (Patton Oswalt) are hunted down to get at the Darkhold book, and only Philip 'Phil' Coulson (Clark Gregg) and the team can save them before the clock ticks out."

The Darkhold is an ancient artifact, a book of all the evil incantations and spells created by a demon named Chton in the Marvel Universe. This book was originally found in Atlantis and was handed down through countless generations until its discovery by a woman named Lucy in our present world.

It is here that the "Agents of SHIELD" managed to track down the whereabouts of the Darkhold Book in an abandoned Alternative Energy Laboratory in Pasadena, California. But they met with some opposition from ghosts in the lab and of course Lucy, who is also transformed into a ghost and continues to hang onto the book.
