DIANE SAWYER TAKES AN EYE-OPENING LOOK AT THE COMPLEX, SOMETIMES VIOLENT LIFE BEHIND PRISON WALLS, ON "PRIMETIME LIVE," THURSDAY, MARCH 24

Diane Sawyer spends a day and a night inside a women's maximum security prison and gets a first-hand look at life behind prison walls in an hour-long "Primetime Live" report. This unique, self-contained world has a culture of its own -- a culture of occasional violence, predatory sex and fear. In the report, which originally aired last November, Sawyer witnesses a disturbing level of mental illness inside the prison, with women kept locked away in solitary confinement to prevent them from hurting themselves and others. She meets some of the most violent, troubled and manipulative prisoners and hears stories that raise intriguing questions about women and violent crime. She is also introduced to the members of "CERT," the crisis management team responsible for keeping dangerous situations from escalating out of control. All the while, Sawyer shares her insights about life "on the inside" in a revealing video diary. "Primetime Live" airs THURSDAY, MARCH 24 (10:00-11:00 p.m., ET) on the ABC Television Network.

DIANE SAWYER, CHRIS CUOMO, CYNTHIA McFADDEN and JOHN QUIQONES are the anchors of "Primetime Live." DAVID SLOAN is the executive producer.
