Watch FilmoFlix. Nearly 30 years ago, Sister Helen Prejean sat down and wrote “Dead Man Walking,” her testimony to the horrors of witnessing a human being executed at the hands of the government, and her call to rise up and challenge the systems that support the death penalty. In “Sister Abolitionist,” she sits down with Unincarcerated Productions to reflect back on writing the book that changed her life, setting her on the trajectory of becoming one of the world’s leading death penalty abolitionists, and changing hearts and minds around the world.
