But his father is ill, and New York City’s distractions have become too much for him. He hopes that a quick visit will help him recharge.

Forty years later, a curious undergrad named Becky Cooper will hear the first whispers of the story --- a tale of gender inequality in academia, a “cowboy culture” among empowered male elites, the silencing effect of institutions, and our compulsion to rewrite the stories of female victims.

When Debora Harding was just 14, she was abducted at knifepoint from a church parking lot. She was thrown into a van, assaulted, held for ransom and left to die. Debora survived.

Denial became the family coping strategy offered by her fun-loving, conflicted father and her cruelly resentful mother. It wasn't until decades later --- when beset by the symptoms of PTSD --- that Debora undertook a radical project: she met her childhood attacker face-to-face in prison and began to reconsider and reimagine his complex story.
