Tess and Brady are planning a haunted house fundraiser so they can expand the shelter to include a top of the art training facility as well as a permanent residence for hard to place animals. During the decorating party they find a skeleton - a real skeleton - hidden behind a false wall in the attic. They turn the skeleton over to Mike but once they do everything starts going wrong and Tess wonders if they haven't somehow managed to awaken an angry spirit. Mike thinks Tess is letting her imagination run away with her but she trusts her instinct so, with Tony's help, she begins to dig around on her own. The deeper they dig the more they find including a second more recent body hidden within the creepy old house.
Meanwhile, Bree and Mike are adjusting to married life, Tess finds out something alarming about her father's life before he met her mother, and plans are underway for another Thomas Thanksgiving.
