Children's comedy drama series. The sighting by Ralph Devlin of what appears to be a ghost in the disused science block forces private detective Fletcher Moon to question his own scepticism about all things paranormal. April then challenges Moon to uncover the truth behind the mystery, so Moon temporarily becomes a paranormal investigator. He and Red are spooked when further 'evidence' of the supernatural presents itself. Armed with gizmos designed to record evidence of paranormal activity, Moon and Red set up a stakeout in the old lab. The evidence builds, with green smoke, creepy red eyes spotted in the window of the science block, and what appears to be a gruesome monster skulking around, but are these phenomena perhaps more 'normal' than paranormal?
