S4, E3: After reporting to the police that she had been raped by one of her classmates, a high-school girl apparently hangs herself in her bedroom. But Brenda is not so sure it's a suicide, especially given that the boy who allegedly raped her is the son of Mark Yates (guest star Daniel Baldwin - "Homicide: Life on the Street"), a Los Angeles County Sheriff's Dept. commander. Despite some major head-butting between Brenda's squad and the overheated and overprotective Yates, Brenda's intense investigation eventually uncovers a ruthless sexual game being played at a local private school.
