Hammer accompanies a conservative politician to Moscow on a fact-finding mission. Arrested and imprisoned by the KGB on a bogus charge; he quickly escapes, creating an international incident by getting into a fire fight with Russian agents. On his stateside return, the government is none too happy with Hammer. Russia is insisting upon his return to stand charges, and various government agencies are following him. A question dogs our hero: why him? Why does Russia want him back, and why was he singled out to accompany the senator to Russia in the first place?
