Ghosts Description, Courtesy of CBS:

Ghosts is a single-camera comedy about Samantha and Jay, a cheerful freelance journalist and up-and-coming chef from the city, respectively, who threw both caution and money to the wind when they decided to convert Woodstone Mansion, which Sam inherited, into a bed & breakfast—only to find it was inhabited by the many spirits of deceased residents who now call it home.

The departed souls are a close-knit, eclectic group that includes a saucy Prohibition-era lounge singer (Danielle Pinnock); a pompous 18th-century militiaman (Brandon Scott Jones); a ‘60s hippie fond of hallucinogens (Sheila Carrasco); an overly upbeat ‘80s scout troop leader (Richie Moriarty); a cod-obsessed Viking explorer from 1009 (Devon Chandler Long); a slick ‘90s finance bro (Asher Grodman); a sarcastic and witty native from the 16th-century (Román Zaragoza); and a society woman and wife of a 19th-century robber baron who is Sam’s ancestor (Rebecca Wisocky), to name a few. The opening of the B&B has been a source of intrigue, anxiety, and curiosity among the spirits, but they will gladly put up with the commotion as long as they can continue to interact with a living inhabitant.
