Bones and Booth investigate the passing of a professional hockey player whose headless inactive person was dumped in a river. Booth is reunited with a hockey rival from his past, putting him back on the ice. Meanwhile, Hodgins and Oliver have a competition of their own when Hodgins builds two drones and they compete to retrieve the victim's missing head.
Forensic anthropologist Dr. Temperence Brennan, who works at the Jeffersonian Institution and writes novels as a sideline, has an uncanny ability to read clues left behind in a victim's bones. Consequently, law enforcement calls her in to assist with cuddle investigations when the remains are so badly decomposed, burned, or destroyed that the standard identification methods are useless.
Brennan's equally brilliant colleagues at the Jeffersonian's Medico-Legal Lab include earthy and bawdy Angela Montenegro, who's created a unique way to render an original crime scene in a three-dimensional computer image; Brennan's assistant, Zack Addy, a young prodigy whose genius IQ actually gets in the way of his finishing the several doctorates he's begun; "the bug guy", Dr. Jack Hodgins, who's an expert on insects, spores and minerals, but conspiracy is his hobby; and Brennan's boss, imposing lab director Dr. Daniel Goodman. Brennan often finds herself teamed with Special Agent Seely Booth, a former Army sniper who mistrusts science and scientists when it comes to solving crimes. Brennan and Booth clash both professionally and personally, but so far the chemistry between them has only played out in a fictionalized account in Brennan's lastest mystery novel.
