A compilation of four episodes from the M.A.D World series, tracing the later years of the Cold War through the weapons and crises that defined it. The centerpiece is the neutron bomb, tested in the Nevada desert and built to unleash a lethal burst of radiation while leaving buildings largely intact, a design engineered to kill people rather than destroy property. Archival footage and news reports carry the story of the panic the weapon caused when it became public, framed against the wider arms race between Washington and Moscow. The episodes move chronologically toward the endgame of the superpower standoff, covering the escalating rhetoric, testing programs, and political maneuvering that eventually gave way to the Soviet Union's collapse. Historians and archival interviews anchor the narration, which favors plain chronology over speculation. Runtime aside, the film works as a survey of how deterrence theory turned into ever stranger and more destructive hardware, with the neutron bomb standing as the starkest example of a weapon designed around a body count rather than a battlefield.
