A lone voice calls out injustice. Rare are the moments when a force of good rises up in everyday life to confront a prevailing evil. Here, the arena is a college classroom, where a rogue bioethics professor challenges common thinking about the beginning of human life. He makes a scientific case for life's starting point and then follows with a judgment on abortion that sparks outrage. Angry students leave in protest while others counter the professor with arguments that range from reasonable to cynical to sinister. As class continues, the debate progresses and tensions escalate. Each side refuses to back down because of what's at stake--the hearts and minds of current generations, the lives of generations to come, and the soul of a society.
