Detectives Elliot Stabler and Olivia Benson find themselves in unfamiliar territory when Doctor Raye Massey calls them in to investigate the case of a baby infected with AIDS. The detectives enlist the help of Dr. Melinda Warner, a member of an AIDS surveillance team along with Dr. Massey. While Dr. Warner investigates the baby's medical case, Detectives Stabler and Benson discover that the baby had been prescribed ineffective vitamins by Doctor Gideon Hutton, who runs a "voodoo" medical practice. After the detectives probe for more answers, similar cases of mistreated AIDS surface, such as the death of Susan Ross' daughter. Her 18-year-old son Tommy Ross also gets pulled into the case, forcing him to decide whether to take on his mother's belief in homeopathic medicine or fight against it. With Dr. Warner's medical research and testimony, the case calls the ethics of Dr. Hutton's practices into question.

Detective Elliot Stabler arrives on the scene of a murder to find a young woman brutally killed, and carrying a rare bird species found dead in her purse. Dr. Melinda Warner comes back with some startling evidence - the saliva found in the cuts on the victim's body shows she was mauled by a tiger. Oscar Assadorian leads the detectives to the victim's twin sister, Anna Bleers who in turn leads the detectives to Hip Hop artist, Gots Money. Gots, who admits to working for an animal smuggling ring, agrees to go undercover with Detective Stabler to catch the smugglers, Andre Bushido and Tybor. But when Detective Olivia Benson poses as a prostitute to help out her partner undercover, Detective Stabler finds himself wounded and his marriage in disarray.
