Featured cases including the investigation of a dating service with ties to a string of recent rapes; the schoolyard shooting of a 6-year-old; and the discovery of a deadly new strain of AIDS. The drama follows Detective Elliot Stabler (Christopher Meloni), a seasoned veteran of the unit who has seen it all, and his partner, Detective Olivia Benson (Mariska Hargitay), whose difficult past -- a product of rape -- is the reason she joined the unit. Captain Donald Cragen, (Dann Florek, reprising the role he played on the first three seasons of "Law & Order" 1990-93) oversees the unit with his tough but supportive approach to the team’s complex cases, guiding the squad through the challenges they face every day. Detective John Munch, (Richard Belzer), a transfer from Baltimore’s homicide unit, brings his acerbic wit, conspiracy theories and street-honed investigative skills to the team.

Assistant District Attorney Casey Novak (Diane Neal) brings closure to the intense investigations with her legal expertise. The forensic psychiatrist, George Huang (B.D. Wong), whose insight into the minds of the accused, often provides significant clues that lead to the resolution of a case, while Medical Examiner Melinda Warner (Tamara Tunie) lends her skills to uncover forensic evidence.
