This is a fairly unique and highly-praised TV movie designed, like Orson Welles' radio broadcast of WAR OF THE WORLDS, as if it were real coverage of a nuclear terrorist event on the East Coast of the U.S.  More realistic than its contemporary, THE DAY AFTER, this film scared the network enough that they kept running disclaimers throughout its presentation stating that it was not an actual news event.  If that description and the subsequent Emmies aren't enough to whet your appetite, I'd say this is just that much more scary in the post-9/11 era. Not a well known TV movie, but it seems even less like fiction now with its urban nuclear terrorist threat and non-stop news coverage of the events.  Worth seeing.
