Dr. Temperance Brennan and FBI Special Agent Seeley Booth travel to Los Angeles to determine the identity of a woman whose body parts were found near Los Angeles International Airport. With Booth at the wheel of their convertible rental car, they are assisted on the L.A. end of the case by young FBI Agent Tricia Finn, who is a little too eager to help. Agent Finn knows Brennan's books inside and out and mentions reading in an entertainment industry trade paper that the film rights to Brennan's latest book were bought by producer/director Penny Marshall. When Brennan and Marshall meet face to face on the set of "Entertainment Tonight," both Marshall and ET's Jann Carl are impressed and a little taken aback by Brennan's dedication to her latest case. Brennan's skills are put to the test when she realizes the victim's identity is hidden by previous extensive plastic surgery.
