When nosy neighbors Henry and Margaret (guest stars Mark-Linn Baker and Kathryn Greenwood) push back on Sam and Jay's (Rose McIver, Utkarsh Ambudkar) plans to open their bed-and-breakfast, the latter couple invites the former to join them for a dinner party, hoping to mount a charm offensive and win their permission in the new "Dinner Party." Naturally, the ghosts of the house are indeed very keen to be included. Brandon Scott Jones, Rebecca Wisocky, Richie Moriarty and Danielle Pinnock also star.
