The body of a man with a white beard and a tailor-made Santa costume is discovered in the sewer near a D.C. mall just three days before Christmas. As the team gathers forensic evidence, the victim seems to match the legend more closely each step of the way. Booth and Brennan discover the man, whose legal name was Kristopher Kringle, was a well respected Santa Claus impersonator, employed by a local Rent-A-Santa business. When Booth and Brennan inspect Kris' apartment, not only do they find his place decked out with holiday cheer, but they also find thousands of dollars stashed in a dresser drawer. As Christmas Day approaches, the Jeffersonian team works to find out who would have wanted this true-to-myth Santa dead. Meanwhile, Brennan visits her father in jail and plots a not-so-traditional Christmas reunion, and Booth and Brennan find themselves in close quarters with the mistletoe just overhead.
