The link I have just Copy-pasted leads to a 1983 TV-movie called Special Bulletin that aired on NBC. The plot was centered around a Realistic fake news broadcast about terrorists taking hostages on board a tugboat in the Naval Yard of Charleston South Carolina. Among the Hostages is the News Network's local affiliates Field Reporter and cameraman. Using them, the Terrorists reveal themselves to be anti-nuclear weapons activists. They want all the detonating modules to the nukes around Charleston, to be disposed of out at sea. The Hitch? If The Detonators are not delivered to them by 4:30 PM the next day, they threaten to detonate a nuke of their own. Watch it first, then let's talk about what would happen next.
