The Hundred Days of the Dragon - The Outer Limits

(4th upload attempt...)
The government of an unnamed Asian country south of Mongolia (in other words, China) has developed a remarkable spying technique: the ability to impersonate any man through physical alteration. This alteration has little to do with surgery, and instead relies on the injection of a drug that makes a person's skin malleable, and like clay can then be sculpted. Add voice training, character impersonation, and the best possible infiltration through body snatching can be achieved.

The shady government's intended target for replacement is William Lyons Selby, the leading candidate for President of the United States. Successfully infiltrating the White House in the guise of President Selby, the shady government can soon put into play its plan for world domination. First by withdrawing American fleets from eastern waters, and then by imitating other members of office, primarily the principled and suspicious Vice President and dear friend of Selby's, Ted Pearson.
