The Threepenny Opera by Bertolt Brecht and Kurt Weill

Set in the slums ruled by poverty, corrupt business practices, and biased justice, the play focuses on the stories of the working class. The protagonist is Macheath, a gentlemanly young criminal ...
Macheath (Mackie Messer, or Mack the Knife) marries Polly Peachum. This displeases her father, who controls the beggars of London, and he endeavours to have Macheath hanged. But his moves are hindered by the fact that the chief of police, Tiger Brown, is Macheath's childhood friend. Still, Peachum exerts his influence and eventually gets Macheath arrested and sentenced to hang.
The play challenges conventional notions of property as well as those of theatre. It asks the central and highly political question, "Who is the bigger criminal: he who robs a bank or he who founds one?"
