Margaret and Liz are sisters who are about to get in over their heads ... They've been gifted The Seahorse Inn, a beautiful bed-and-breakfast by the beach in Cape May. Though it hasn't been open to guests in years, the pair endeavor to reopen in time for the holidays. Problem is, they discover the charming old place is really a money pit full of more issues than they can handle on their own. On top of dealing with renovations, Margaret is surprised by an unexpected visit from her ex-mother-in-law. Having never gotten along, Elaine has a lot of nerve to request Margaret step in and do something about her ex-husband giving his mother the slip. Not only that, but the neighbors who own the Morning Dew Cottage next door are nothing but nasty and rude, which is a mystery to the sisters. As Margaret and Liz get to know their other neighbors, they uncover hidden secrets within the Seahorse's walls. Dave and Margaret are still going strong, but will his brash mother and big family feud over the holidays prove to be the straw that breaks Margaret's back?
