The disfigurement of a doctor's wife leads to the discovery of a murder under similar circumstances from the past.


When Lisa Ross is brought into the emergency room with a severe case of chloracne, suspicion quickly turns to her husband Greg, a well-known dentist, especially after she dies. During their investigation, Goren and Eames hear whispers about Lisa's infidelities, but the real break comes when they learn that Lisa was not the first woman to whom Greg Ross had been connected who had died of the same symptoms.


Dr. Gregory Ross' wife, Lisa Ross, is mysteriously poisoned with dioxin and ultimately dies from the poisoning. The culprit turned out to be one of her pub quiz group partners, Colleen Dexler. Colleen Dexler knew Dr. Greg Ross from years before when he was engaged to her prettier sister, Morgan Dexler. Little did Dr. Ross knew Morgan was cheating on him. He ultimately found out, had a private investigator prove it and killed her via dioxin poisoning. Ross eventually married again, this time to the beautiful Lisa but she too was unfaithful. Instead of Ross finding out, Colleen found out and was in actuality the one Lisa was cheating with via an online relationship. She persuaded Lisa, under the guise of being Lisa's online "suitor", to insert a mixture of cocaine and dioxin within her vaginal cavity. Thus, Lisa was poisoned with dioxin. When Ross was about to go down for both murders, he pointed the detectives in the direction of Colleen. Colleen eventually confesses she was the one to poison Lisa but that she didn't kill her sister, although she didn't say it was Dr. Ross either, although she knew. The police knew Ross killed Morgan Dexler however and he too went down for murder. Before being led away, she admits she killed Lisa because only she truly loved Dr. Ross and that it was her mother's fault that Morgan was dead because Colleen never would have cheated on Dr. Ross but the mother just HAD to push Morgan into Dr. Ross' life. Carver thought Dr. Ross probably was in heaven having landed two beautiful women on separate occasions but Goren concludes the episode by saying "Beauty, it's a beast."
