There's a deer sorting Christmas decorations in the kitchen... Maura has ex-husband trouble. It’s Maura’s first Christmas as a single mom in her ancient castle in Ireland, but her step-kids won’t follow the custody agreement. But when the school carpool shows up with an extra second-grader and his “dog,” Maura can see through their illusion and suspects that her castle has opened the Veil again. While the teens escalate the conflict with their birth parents and Maura’s ex-husband threatens her custody arrangement, one thing is clear: this child needs a home and Maura’s door is open. Maura focuses her anxiety on de-enchanting her visitor, who turns to be the former queen of this same castle. Eager to help, Queen Saba accidentally pulls them both back to her own time, where Maura recognizes the signs of a failing marriage and a husband’s impending betrayal. Can Maura rescue her new friend…or is Maura herself so tangled in the White Deer's fate that she won't survive to make it home to her children?
