Every Christmas, Reilly Shore picks a spot on the map and takes a trip. This year, that destination is the quaint hamlet of Mistletoe Lake. As she arrives, Reilly discovers that the town's lone b&b is chock-a-block full due to Mistletoe Lake's annual Christmas Harbour Festival, with all the boats docked along the water being decorated with festive lights. When twelve year-old Emma invites Reilly to stay on her dad's boat, she learns that Emma's dad Raymond Mitcehll is the only boat owner on Mistletoe Lake who doesn't participate in the harbor festival. In fact, he's in the process of trying to sell his. As the possibility of the sale saddens Emma, she enlists Reilly's help to convince Raymond to enter into the festival so they can have one last perfect Christmas on the picturesque lake...
