Mel Hargrove has one mission tonight--to formally invite her dead relatives to her upcoming wedding. It should be easy enough, with her friend opening the portal, Mel's mother running interference, and the groom-to-be, Becker, promising to stay by her side no matter what. But things rarely go smoothly at Hargrove Junkyard, a place filled not only with junk but with a bunch of ghosts who have not yet passed over to the Good Place. So when a new menace arrives on the scene, taking her ghostly friends hostage and trying to run roughshod over her business, there's only one thing for Mel to do--call in the troops and go to war, right after she deals with her irritating grandmother.
