M.J., her boyfriend Heath, best friend Gilley, and the rest of the Ghoul Getters crew are back home in Boston. Their new film’s a monster hit, and a museum is getting in on the action with a special exhibit of supernatural artifacts. Unfortunately, Gilley-whose mind is engaged with wedding plans-donated the dagger which keeps the demon Oruç locked in the lower realm. Before M.J. can recover the bewitched blade, there’s a murder and a heist at the museum, and the dagger is stolen. Now Oruç, having already killed once, is coming for M.J. and Heath, and the demon is bringing with him some fiendish friends from M.J.’s haunted past. She and the other Ghoul Getters are in for a devil of a time. M.J. may even need to recruit a certain psychic friend from Texas to help stop the paranormal party crashers from turning Gilley’s wedding bells to funeral knells...
