Brennan and Angela party at a dance club called "The Bassment." When Brennan comments about the music being "tribal," comparing it to Indonesian Gamelan Music and Tibetan Throat Singers, a club patron starts an argument with her. Brennan and Angela get caught up in the melee and Brennan kicks someone into the wall, causing it to break open to reveal a mummified corpse and a stash of methamphetamine.Special Agent Patrick Furst is investigating, when Booth shows up with Tessa - they had been on a date when Booth got the call. Booth notices Brennan is acting strangely. Agent Furst informs him that Brennan and Angela are "stoned" - when the wall split a cloud of methamphetamine dust covered the dance floor. Brennan, high as a kite, announces that she is thrilled to be working on her "first modern mummy."
Back at the lab, Brennan has determined that the victim OD'd. He died of asphyxiation from inhaling meth powder. It appears the victim was trying to squeeze through the narrow space inside the wall when a bag of meth burst open, coating the alveoli in his lungs making breathing impossible. Hodgins indicates that judging from the acrid mites in the victim's ears, it appears the body has been inside the wall six weeks.
Brennan re-hydrates the mummy's hands to get fingerprints. Brennan apologizes for ruining Booth's date. Booth divulges that he and Tessa were planning their first vacation together. Booth matches the victim's prints to Roy Taylor (a.k.a DJ Mount). Angela tells Brennan that Roy Taylor was one of the best DJ's in DC and that when he disappeared he was just starting to break.
At the FBI Booth speaks with the owner of The Bassment, Randall Hall, accompanied by his bodyguard. Hall paints a picture of DJ Mount as someone who, like many of the young artists Hall's record label works with, grew up on the street and had trouble with drugs and the law. Booth wonders if Mount had any rivals. Hall dismisses his bodyguard and reveals that DJ Mount, indeed, had a growing rivalry with another DJ from the club, Simon Rulz.
Brennan returns to the club with Zack. Inside the wall, Brennan finds footprints in the dirt indicating someone was on the other side of DJ Mount. She also finds dried blood smears on the wall and what looks like a jeweled earring, meaning someone else was inside the wall with Mount.
At the lab, Angela points out that the earring is actually a belly button ring. Hodgins has pulled particulates from DJ Mount's re-hydrated eyeballs and found low-density polyethylene residue and methamphetamine crystals. Polyethylene is from plastic bags. Based on the damage to the inside of DJ Mount's lips Brennan determines that DJ Mount was murdered when someone smothered him by pushing a plastic bag of meth crystals up against his face. Booth thinks it may have been the owner of the belly ring. Just then Angela enlarges an image of the belly ring and finds an inscription - "Luv Rulz."
Booth and Brennan pay a visit to Simon Rulz at his music studio. They learn Mount dissed Rulz on one of his tracks. Booth wonders if Rulz's girlfriend helped him get back at Mount. Rulz says the girl he gave the belly ring to, Eve Warren, wasn't his woman anymore. He mentions that Eve has a daughter her brother is raising. Brennan notices Simon Rulz's hand is injured. He got shot through the wrist a few years ago. It shattered the lower radius and pisiform, damaging the nerves in his hand. Rulz tells them Eve had a taste for meth and suggests she was ripping Mount off for it.
At the lab, Zack has discovered damage to the facet joint and foramen on C-4 on the right side of DJ Mount's neck - that suggests his head was forced that way. There is also a slight depression on his skull, barley discernible - which could be congenital or a bone anomaly.
Booth and Brennan meet Eve Warren's brother George at his Krump dance studio. George tells them that Eve dropped off her daughter Maya about six weeks ago. He says Eve left some money and that he hasn't seen her since. George reveals Eve had problems, drugs, hanging out with the wrong people. He's very protective of Maya, says he's not going to let anything happen to her. He tells Booth and Brennan that Eve said she loved Mount. That he had promised to give her and Maya a good life. Booth trades George for some of the money Eve left behind.
At the lab, Hodgins has tested the money Eve left behind for her brother and found that it contains the same meth as was found inside the wall. Brennan and Angela show Booth a rendering of the crime scene. Angela simulates a scenario on the computer that proves Eve Warren could not have killed DJ Mount. Eve and DJ Mount were traveling through the wall sideways. Eve was on Mount's left, traveling ahead of him. Mount's neck was twisted to the right, behind himself. This tells them there was a third person in the wall that surprised them. Mount's body blocked the way for this person to reach Eve, which is why she was able to escape. This third person is the one who killed Mount.
Booth is at the FBI with Randall Hall's bodyguard. Booth has figured out that the bodyguard is some kind of undercover cop. His name is Special Agent Robert Oakes and he's been working undercover for the FBI looking for links between the urban music world and the record industry. Oakes tells Booth Randall Hall's real name is Terrence Baskin, who racked up a lot of bodies when he ran the Naylor Road Crew. FBI knows Hall is moving meth through the club, but they can't get enough to touch. Informants get killed or disappear. Oakes reveals that the night Mount went missing Hall got ripped off for a mountain of meth and cash. Hall looks like a he's behind the killing.
At The Bassment, Booth and Brennan face Hall, who tells them he is a hundred percent clean now. Hall denies killing Mount and claims Mount was just starting to make him money. Again he points the finger at Simon Rulz, telling them the rivalry between Mount and Rulz was indeed strong enough to lead to murder. He suggests they might want to check out the new music studio Rulz built for himself. He tells them Eve's missing, and that Rulz poured the cement for the studio the day after she and Mount disappeared.
Booth and Brennan, with Tutti, a cadaver dog, execute a search warrant on Simon Rulz's music studio. Tutti starts barking wildly, she's found something under the cement. Brennan tells Booth to get a jackhammer.
Back at the lab, dental records confirm the body found is Eve Warren. Up in the lounge, Tessa has brought Booth a change of clothes. Angela and Tessa talk about Booth and Tessa's upcoming vacation to Jamaica. Angela scares Tessa off when she suggests they are so ready for the Pre-Shacking Up Test Vacation. Brennan shows up and tells Booth that Eve Warren was killed by the same method as Mount, meth overdose. Brennan also tells Booth that she doesn't think Simon Rulz killed Eve, despite her being buried underneath his studio. Why? Because Eve Warren's wrist is broken.
Using the Angelator, Brennan and Angela show Booth how Eve was killed. She was taken from behind and smashed into the wall. Her skull shows damage to the infraorbital and supraorbital margins and the zygomatic process. A bag of crystal meth was then ground into her face. Her right arm was twisted behind her separating her ulna from the scaphoid and trapezium. The person who killed her had to have the strength to use both of their arms in the attack. The significant nerve damage to Simon Rulz's wrist rules him out as a suspect.
At the FBI Booth and Brennan interrogate Simon Rulz who finally gives up that Mount got killed because he was going to leave Bassment Records. All he needed was money to buy himself back. Rulz tells them Eve couldn't kill anybody and that Randall Hall built him a new music studio the day after Mount and Eve went missing. That's all the information Rulz can give, otherwise he says he'll end up a dried out mummy in a wall too.
At the lab, Zack finds a mark on Eve Warren's manubrium that matches the mark they found on DJ Mount's skull. Brennan determines the mark was caused by something external. Booth is now convinced that Eve Warren was a woman in love who ripped off Randall Hall so she and Mount could start a new life together. He believes that Randall Hall killed them. Booth and Brennan arrive at The Bassment and confront Randall Hall. Hall denies killing DJ Mount and Eve Warren. Booth pushes Hall's buttons and Hall pokes him with his cane. Brennan sees the tip of Hall's cane, realizes she may be looking at the murder weapon and tells Booth to arrest Hall and seize the cane as evidence.
At the lab, Zack and Hodgins match a mark from the end of Randal Hall's cane to the marks on DJ Mount's skull and Eve Warren's manubium. Brennan finds out from Angela that Tessa freaked out and has bagged on her vacation with Booth vacation to Jamaica.
