Seismic. Johnny Douglas, ex-Marine sniper and now a very content Forest Ranger in Yellowstone is curious as to the unusual number of helicopters flying over the northwestern and fairly untraveled area of the National Park. Deep in the isolated part of Yellowstone, Jacqueline Valois, PhD in volcanology is unhappily ensconced in a secret compound. She thought she had come to the US to study the super-volcano. Being curious, and a bit foolhardy, she has discovered her "employers" intend to use nuclear devices to blow up the volcano; an eruption that would cover one third of the US in volcanic ash. Just when she and fellow PhD, colleague Fred Peters, find the actual "nukes" Fred is shot and killed. Jacqueline escapes but is soon captured. Snowmobiling through the forest, Johnny is accosted by snipers in white ski suits. Though he fights back, he is taken prisoner and place in the same room with Jacqueline. The two break out of their "prison" and wreak havoc on the compound. But are they any match for three nuclear devices set to explode in the next eight hours? Can they find them? Or will the egomaniac Mahmoud Hussein, the terrorist leader, find them first and strap them to the bombs as he has threatened? Written by Catherine Lanigan and Jed Nolan.
