Based on the 2023 Vanity Fair article "True Crime, True Faith: The Serial Killer and the Texas Mom Who Stopped Him." "Fear Not" tells the story of prolific serial killer Stephen Morin — accused of more crimes than Ted Bundy — and the unlikely bond he formed with Margy Palm, the last woman he ever kidnapped. Morin’s abduction of Palm, which started as a deadly captive situation, took an unlikely turn; one which included compassion, prayer, and profound courage. Palm’s devotion to her faith and her insistence that Morin could be transformed, became the impetus of a relationship that lasted long after Palm was returned to safety — until Morin received the death penalty.
