A documentary about two men in their seventies with a bond between them – both Holocaust survivors and Czech/American émigrés, who left Prague as dissidents under the Communist regime. Jan Wiener, 77, is the fighter of the title, a fit, trim university literature professor abroad and wilderness guide at home, in Lenox, Massachusetts. Arnošt Lustig, 72, in addition to being a professor of film and literature at Washington University, is a celebrated Czech author and scenarist. The two Jewish men met in the U.S. in 1978 and they became close friends. The film essays their friendship and, perhaps also its likely dissolution. The occasion for the falling-out is a journey the two take in the Czech Republic, Slovenia and Italy, retracing Wiener’s escape from the Nazis. Lustig accompanies Wiener because he has long wished to write a book about his friend’s life. But this attempt, ironically, brings up all the differences between the two men, not only in terms of their personalities, which have always clashed in bouts of genial bickering, but also in their pasts, their very lives.
