The Smith-and-Smith Paranormal Investigation Agency has investigated many different types of buildings and edifices over its many years of operation; not just haunted house. They have investigated schools, ski-resorts/lodges and hotels, but they have yet to investigate an abandoned insane asylum, until now. They are drawn to the Edgewood Home for the Criminally Insane in upstate New York, bringing their three children; William, Oscar and Carol Anne along, but they get more than they bargained for when a few of these lost souls follow them home after the investigation including the sole of a young girl supposedly murdered in the halls of the insane asylum when it was still in operation

Bill and Erica Smith's three children; William, Oscar and Carol Anne have been going on paranormal investigations with their parents since they were babies. Now that they are getting older, as William approaches being a preteen as he turns 10 in March 2028, he and his 7 year old brother; Oscar want to get into the "family business", and they start with Oscar's friend; Bradley Appleby who they think lives in a haunted house when Oscar goes to his house for a birthday-party. The boys then hatch a scheme to conduct their own investigation outside of any help from their paranormal investigator parents, but they find that they have a lot to learn before they can take over the "family business", from their parents.

William and Erica Smith are back, for more paranormal investigations.At first, they remain part of "The Paranormal Society of America", but as more and more of their neighbors come to realize that they are paranormal investigations, Bill and Erica decide that it might be best to leave "the Society", and start their own practice as paranormal investigators but it remains to be seen if their experience with "the Society", will end up paying off, now that they're in business by themselves.

The Smith and Smith Paranormal Investigation Agency has been investigating all sorts of paranormal entities and manifestations over the years but when Erica Smith buys her daughter; Carol Anne a bunny costume at a garage-sale, they find out that they got more than they bargained for as they have to investigate their first case of a haunted object; their daughter's bunny costume, where they trace it back to the owner of it having been killed while wearing it, out trick-or-treating several years earlier

Every family has their family traditions when it comes to the holidays and especially the holiday of Christmas. For Suzanne and Bill, ever since they became parents, that included decorating their "humble abode", and putting up their massive Christmas-tree. As their family grows, with the birth of their daughter; Elizabeth, son; Oliver and their twin daughters; Candace and Carol Anne, so do their traditions, adding new ones along the way; ones that they'll cherish until the end of time.
