Drew [=McDaniel=] is found unconscious on a park bench, seemingly the victim of a mugging. But when he is taken to the hospital, doctors find that he has had one of his kidneys stolen. Logan and Greevey investigate the incident, talking to a doctor who tells them it is illegal to sell or buy an organ. Most organ transplant patients can take drugs to prevent their bodies rejecting the new organ - unless they have a specific condition that means the drugs won't work, and the person requires an exact match. This leads the detectives to the patient who received [=McDaniel's=] kidney: "Mary Merritt", real name Joanna Woodleigh.

Joanna is the daughter of the very wealthy philanthropist Philip Woodleigh, and her drug abuse caused her own kidneys to fail. The detectives track down Dr. Reberty, the surgeon who carried out the transplant. He and his assistant are charged with attempted murder. A member of the board of directors of the Organ Transplant Network reveals that Woodleigh offered a large donation if Joanna were given priority for a kidney. The director refused, feeling that money shouldn't buy life. He encourages the detectives to prosecute Woodleigh as well.

Reberty takes a plea to testify against Woodleigh. In court, Reberty says that Woodleigh wanted a kidney for Joanna "whatever the cost." He paid Reberty over a million dollars to find a kidney and perform the transplant. Joanna tries to convince Stone to drop the charges, since the transplant gave her a second chance at life, while [=McDaniel=] is still alive and her father will pay him well. Stone refuses, saying that Woodleigh would have done the same thing if Joanna needed a new heart.

The prosecutors then learn that one of Woodleigh's shell companies bought Reberty's foreclosed house for ''another'' million dollars - twice its market value. So there must be something more Reberty is keeping quiet about. Under threat of rescinding his plea bargain, Reberty produces a recorded phone conversation with Woodleigh. During the call, Reberty said that [=McDaniel=] was a match for Joanna but wouldn't agree to donate a kidney; Woodleigh ordered Reberty to do ''anything'' to get the kidney, even kill [=McDaniel=]. Woodleigh is convicted of attempted murder.
