Brian Roy is the brainchild behind the Leonidas Group, a ghostbusting organization with a track record of incomparable success for tracking down and annihilating ghosts. This time, however, Brian may have met his match with his latest job investigating Middlebury Sanitarium! Occupied by a host of undeads, Middlebury Sanitarium has a history of drugging its residents to prevent them from entering the grounds at night and becoming a part of the "lost brigade" never to be heard from again. From a vengeful King who ruthlessly protects his royal domain, to Clyde a faceless soldier who's still fighting WWI-Brian's got his hands full! And then there's the boneyard...

Now, Brian teams up with an old vet caretaker, Ken Buckingham, to de-ghost the place. But the shrewd, kindly old man has a few secrets up his own sleeve that even Brian could have never anticipated.
