Shawn and Gus go undercover as teachers of the paranormal at a school for gifted kids to investigate a possible murder. The only problem is, their clients, two students at the high school, don't have any idea about the identities of the murderer or his supposed victim. All they have to go on is a phone call they accidentally overheard a few nights ago while inside the school.

Meanwhile, Juliet's one-year probation period has ended, so she grabs the reigns and leads her own case. Coincidentally, the case that Lassiter gives her is the same one Shawn and Gus are working on.
