In Howard Fileman's house, which is for sale, estate agent Katie Selnick and two prospective buyers discover a corpse, charred except for a fat foot. Clever forensics gradually show it was actually two people, a fat man and PriceCo saleswoman Meg Tracy, who recently lost half her excessive weight and met her lover in a fetishist club. Seeley however is greatly distracted by a surprise visits from Hank 'Pops' Booth, who left his retirement home after hitting a male nurse and now tries to "correct" Booth's life, but rather lost control of his own.

Post staff finds several mail boxes filled with goo - actually a chopped-up human corpse. Their address labels were deliberately messed up so as to strand them in a specialized post office, but a code traces them to a local Ship 'n' Print, where one employee is missing and proved to be the victim. Most of his colleagues resigned after jointly winning a fortune in the lottery. Sweets helps cut trough their endless lies. Booth gets a surprise visit from grandpa, on account of the death of Seeley's ever-absent father, which he's most unwilling to discuss. Bones leaves most of the field work to Booth's ambitious FBI cadet Genevieve Shaw, to accommodate her pregnancy, which renders Clark most uncomfortable.

Brennan and Booth are to be married tomorrow, but not without a murder to solve. The team calls in all interns to help with the case so Brennan does not have to do anything.
