When a female psychiatric doctoral student is found raped and murdered and an unidentified man stabbed in a neighborhood market, several of her counseling patients are pursued as suspects. One patient had been stalking the murder victim, and another had her support in refusing to take medications that caused severe side effects. Detectives Benson and Stabler and Detectives Munch and Tutuola offer varying opinions regarding mandating medication as they follow all leads and discover that the stabbing victim may not be revealing everything he witnessed at the crime scene.
