 A group of scientists, working in a deep underground lab, clones and hatches a 1,000-year-old dragon, after finding its remains in a cavern in southern England. After the critter goes from one cell to full grown in 3 hours, it goes on a rampage, killing most of the scientists and escaping to the surface. Naturally, bullets don t faze it at all. Our Intrepid Hero helps kill if before it can menace all mankind. Sort of "Alien" meets "Reign of Fire".
