Thomas "Babe" Levy, whose brother Henry James "Doc" Levy is an oil business executive, is a Ph.D. candidate in History at Columbia University. He is also training as a marathon runner. Babe is paying homage to his deceased father, H.B. Levy, in pursuing the same studies as he, the father who committed suicide while being under investigation in the Communist witch hunts. Babe's work does not sit well with Doc who wants Babe to move on with his life. While at Columbia, Babe meets and begins to date Elsa Opel, a foreign exchange student also in History. While out for a walk in Central Park late one night, Babe and Elsa are mugged, the unusual aspect of it being that their attackers were men in suits. Babe will learn that the mugging was not a random attack after someone close to Babe is found murdered, the deceased whom was not whom he purported to be. From here, Babe is thrown into an international conspiracy concerning Nazi war criminal Christian Szell in hiding, and a large cache of diamonds. In the process, Babe learns that Szell's associates are after him believing that he was passed sensitive information by the deceased before his death. Not knowing anything about what's going on, Babe has to decide whom he can and cannot trust while he works to find out what's going on. In Babe discovering what's happening around him, his issue with Szell becomes personal.
