In a castle in Falkonmatt, Switzerland is a very special laboratory where the half-invalid and completely mad genius Tabor Ulrich has devised cybernetic organisms indistinguishable from human beings. He has also devised a computer capable of downloading the contents of a human brain into its memory. With these tools he makes a perfect copy of Admiral Nelson, the first step in his plan to correct the world's flaws by placing its governments under the control of an array of his cyborgs. And if the world won't agree, he'll use his false Nelson and the Seaview's
nuclear missiles to force compliance!
