Synopsis by Sandra Brennan
Originally aired as an epic mini-series, Doomsday Rock was the first revival of "what-if-an-enormous-(insert appropriate astral body)-hit-the-Earth" movies. Essentially a sub-genre of the disaster movie, the story centers on the struggle of one main character to save the planet while simultaneously presenting on-going vignettes following the predicaments of secondary characters. Famed astronomer Dr. Paul Sorenson has been studying the ancient paths of comets for most of his career; he knows that comets and large meteorites have hit our planet before and believes such impacts caused the mass extinctions of the past. According to his latest calculations, a large comet is due to collide with our planet very soon. Unfortunately, nobody but his daughter, also a respected researcher and astronomer, believes him. Desperate to save humanity from mass extinction, Sorenson and his few followers commandeer an nuclear silo.
