"Fallout" 1994 tells a story dramatizing the intense political events leading up to New Zealand's groundbreaking anti-nuclear stance in the 1980s. The mini-series focuses on the period around the 1984 snap election, where David Lange's Labour Party came to power on a strong anti-nuclear platform. It explores the pressures faced by Lange from both domestic forces and the powerful United States administration, which vehemently opposed New Zealand's decision to declare itself nuclear-free and effectively sever its defense alliance with the U.S. The narrative delves into the political maneuverings, internal party conflicts, and the determination of figures like Marilyn Waring, an MP who defied her own party, to solidify New Zealand's independent foreign policy on nuclear weapons.
