Melinda believes that some old war antiques she has are haunted. When she goes back to the man who sold them to her, George Mastersargeant, he gets very anxious and won't answer her questions. She becomes even more convinced when she has a vision where she steps on a landmine and everything explodes and starts seeing a ghost boy who seems to be playing soldier. Suspicious, she and Eli follow George Mastersargeant to an old, abandoned army base. Melinda discovers George was simply stealing artifacts from the base. She once again sees the little boy but he eludes her. When she sees him again, she finds him holding what is an old land mine from Vietnam. Melinda becomes a little confused because she doesn't see any evidence of her ghost boy being killed by the bomb and when she goes back to search the base again, she discovers the body of her ghost boy in an airtight container. She finds out the boy was missing for a couple of days and had gone to this base because his father, a soldier who was killed in Afghanistan, used to take him there. The last time the ghost boy, Joey, was there, he wanted to take one of the land mines as a souvenir but was startled into hiding when he heard someone come. The container he was in closed on him and he suffocated but not before seeing Professor Bedford take one of the live bombs. In the meantime, Professor Bedford is demanding the Book of Changes from Eli, Melinda and Ned so he calls from Delia's real estate office telling them to bring the book to him or the bomb he has will go off. Eli brings the book and frees Delia. When Professor Bedford finally has the book in his hands, he's horrified to find that the book erased itself and the Shadows get angry, setting off the bomb blowing up him and Delia's office. Melinda crosses Joey over and reunites him with his father. The Book of Changes puts itself back into another one of Ned's Economics books.
