Howard and Raj try to get to the bottom of why Sheldon disappears every afternoon at 2:45. Meanwhile, Leonard and Penny wrestle with jealousy in their relationship.

Everyone is a suspect when a body is found murdered at a popular nightclub known as "The Lab." In an unusual twist of storytelling, Brennan, Booth and the Jeffersonian team take on various roles outside their normal duties, including serving as the nightclub staff as well as local law enforcement. A slew of special guest stars, including Max Keenan (guest star O'Neal), Jared Booth (guest star Fehr) and the members of Mötley Crüe, pay a visit.

Booth and Brennan are on the case when shattered, pulverized human remains are found in a garbage bag at a photo shoot. When the team discovers a meteorite shard lodged in the victim’s ear, they are led to the Collar Institute of Science, a famous center for physics research in D.C. After questioning scientists at the institute, they discover the remains are those of Dr. Diane Sidman, a leading scientist and editor-in-chief of the Journal of the Collar Institute, who was also engaged to the Collar’s founder. When they discover Dr. Sidman had been working on an extremely controversial project, Brennan and Booth investigate a multitude of death threats directed at her. As the team tries to decipher the cause of her death, Booth and Brennan are on the search for the killer, but their scientific method leads them into a dangerous situation. Meanwhile, Angela’s father (guest star Gibbons) comes to town to seek revenge on Hodgins, and Sweets attempts to mediate the situation.

When skeletal remains are found in the Chesapeake Bay, Brennan and Booth are on the case to investigate. With only the upper torso of the victim intact, the team has little to work from besides the remnants of the victim's breast implants. Brennan and Booth are led to a small church community in Maryland where the victim was a pastor, but they have no record of her existence prior to moving to the small town five years prior. When the victim's lower half is discovered, the team realizes their initial assumptions about the victim may not be correct. As Sweets lends insight to the victim's psychological state and Brennan's latest grad student adds his own offbeat observations, the team must decipher who would have wanted her dead. From possible love interests to her family to the parishioners at the church where she was a pastor, the anatomy of the case is very misleading.

When sniper-on-the-loose Jacob Broadsky (guest star Arnold Vosloo) claims another victim, Booth becomes more determined than ever to catch his elusive foe. After a bullet meant for Booth strikes an innocent victim, Booth makes it his mission to catch Broadsky once and for all.
