A man dressed as Santa Claus wearing an explosive vest is blown up via a radio frequency after robbing a bank, leaving Booth and Brennan to investigate the identity of the bomber and who set off the explosives. Brennan plans on spending Christmas in El Salvador, but her father (Ryan O'Neal) convinces her to stay and spend it with him and one of her distant relatives, Margaret (Zooey Deschanel). After solving the case, the Jeffersonian team attend the funeral of the man that was killed after they discover he was forced into the robbery, comforting the mother who was his only family. The team later celebrate a Christmas dinner at Brennan's.
