Ground Zero (The X-Files)

Dr. Gregory, a renowned nuclear weapons researcher, is not only dead-- he's been charred to a radioactive cinder. Since this is a death on federal property, Agents Mulder and Scully are hastily called in. When a second victim, completely unrelated to nuclear science or to Gregory, is obliterated in the New Mexico desert and then a third dies the same way in Washington, DC, Mulder and Scully begin to focus on the frightening dimensions of their task. The bizarre deaths cannot be a coincidence. And as they work to uncover the secret element that unites these deaths, it becomes clear that this twisted puzzle has fatal consequences for the entire world.
