Franz Biberkopf, pimp and petty thief, has just finished serving a term in prison for murdering his girlfriend. He's on his own in Weimar Berlin with its lousy economy and frontier morality, but Franz is determined to turn over new leaf, get ahead, make an honest man of himself, and so on and so forth. He hawks papers, chases girls, needs and bleeds money, gets mixed up in various criminal and political schemes in spite of himself, and when he tries to back out of them, it's at the cost of an arm. Though Franz is more dupe than hustler, in the end, well, persistence is rewarded and things might be said to work out.
