A mysterious seller lists his gaudy, bizarre mansion on a private lake with up-and-coming real estate agent Emmett Thatcher. It's an unusual listing, one with a fantastic commission attached to it--the kind new realtors don't usually get. Emmett's already in town for the funeral of his estranged father's fiance, and the seller offers to let Emmett stay there until the sale closes. When his attempt to reconnect with his father doesn't go well, he reaches out to an old friend named Alexis (affectionately named Fish). In need of a break from her own circumstances, she agrees to join him at the house. It turns out the mansion has a reputation for more than just bad decor--it's haunted. But what haunts the house is not what they expect.
