Plot: Bill Whitaker presents a new double-length segment where Chanel Miller, the sexual assault victim previously known as “Emily Doe,” whose victim impact statement was read by millions before the modern #MeToo movement caught fire, tells her story for the first time. She recounts her ordeal after she was assaulted by a Stanford athlete and describes a judicial process she says victimized her all over again, produced by Graham Messick and Jack Weingart
