Booth and Brennan investigate the scene where a body was uncovered during a botched practice police raid. The team identifies the body as a struggling inventor's father who had recently reunited with his son. But when a second body surfaces, the team is led on a trail of deception to find out who was the actual con-man in the inventor's life. Clark Edison returns to the lab, and he and Hodgins work on piecing together blueprints from one of the inventor's potentially valuable inventions. Meanwhile, Booth's younger brother Jared moves to D.C. to take a job at the Pentagon, and Brennan, smitten with Jared, agrees to go on a date with him to a White House function. Her date with Jared leads her to learn information about Booth's past and give her a far greater understanding into her partner's motives.

When Brennan, Hodgins and author Thomas Vega are summoned by a Federal Judge along with the United States Attorney regarding the ongoing investigation of the Grave Digger, they learn that evidence from the case has recently gone missing. With Brennan and Hodgins having been victims of the Grave Digger and Thomas Vegas currently writing a book about it, they become prime suspects in the missing evidence case. However, when Brennan and the team receive a phone call from the Grave Digger informing them that Booth has been buried alive with only 24 hours worth of oxygen, the Grave Digger threatens to leave him to die unless Brennan brings the missing evidence. The team immediately goes to Booth's apartment to assess the crime scene, knowing from Sweets' psychological assessment of the Grave Digger that they cannot tell the authorities about the situation or else the Grave Digger will retaliate against Booth. As Booth struggles to free himself from confinement, the team joins forces to locate him with precious time ticking away.

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.

When a human body is found inside the strung up Otter mascot uniform of a rival school, Brennan and Booth investigate whether the body inside the costume was dead beforehand, or killed during a Middlesex University bonfire event. The body is identified as Jimmy "Beaver" Bouvier, a fraternity brother at Middlesex University. When Brennan and Booth question his fraternity brothers to gain information as to how he ended up in the rival school’s mascot uniform, they learn that Beaver had a money-making operation on the side and was making a killing of his own. Meanwhile, Booth offers to help his brother Jared (guest star Brendan Fehr) find a new job after being dishonorably discharged from the Navy for illegal activity he engaged in to save Booth's life recently.

When a human skeleton is discovered in the trenches of an old Civil War battleground, Brennan and Booth are called to the case. Despite the historical location, Brennan quickly identifies the bones as belonging to Dan Pinard, a present-day local dentist. While Booth investigates suspects, including the victim’s former boyfriend, Hodgins and lab intern Vincent Nigel-Murray (guest star Cartwright) work doggedly to clean the bones of a stubborn clay residue which is preventing the team from determining a cause of death. Meanwhile, Booth’s brother, Jared, (guest star Fehr) returns from his travels with some suprising news.
