On trying to get to the bottom of her sister Arlene's illness, Eleanore made an astonishing discovery. Half submerged in a frozen lake in a huge underground crevasse beneath Mount Glatz was a colossal abandoned structure which might possibly be the remains of an ancient civilization…or even traces of extraterrestrial activity… However, the place was also home to huge quantities of cryogenic material, which then infected Eleanore who fainted, gradually turning into a block of ice. Fortunately, her weasel set off to warn Arlene who took her sister to see Doctor Drak, who was able to stop the illness from advancing any further with his new serum. And although the two sisters now share the same fate, the mystery of cryoplasma is perhaps a little closer to being solved.
