When a disease-ridden body is discovered in the smouldering ruins of the federally funded DyMar genetic research lab, agents Fox Mulder and  Dana Scully fear a deadly man-made plague may be on the loose. Racing to contain the lethal virus before it can spread, Mulder and Scully make a chilling discovery in the X-Files: The late Dr David Kennessy, a hotshot cancer researcher at DyMar, had been experimenting with microscopic  bio-machines that can cure any disease, heal any wound. In theory, this could be a miracle cure – and the doorway to immortality. But when a second corpse turns up, savagely mutilated from within, it’s anything but theoretical.
