Wha is the play "Asinamali" about?

The play "Asinamali" is about the lives of five imprisoned South African men during the reign of apartheid in the country which divided and oppressed the people—much like the Jim Crow era of the United States. The play is essentially the backstory of the five men, who describe how they have come to be in prison, and was inspired by the 1983 rent strike in the nation. The title is a Zulu word meaning "we have no money," which was the rallying cry behind the strike, as the individuals were forced to pay exorbitant rents and couldn't afford any sort of decent housing.
Originally, the play was unscripted, being simply a directed and presented improvisation act between the five characters. It is simple in form, primarily using and focusing on these few actors, but its energy and passion are what made it famous, with the men shouting and pantomiming with vigor to explain their histories and backstories. The men all describe in vivid and passionate detail the events surrounding their incarcerations, which all stem from racism and unfair enforcement of certain laws that target the black community much more severely than the white community in South Africa.
In addition to their backstories, it also explores their lives in imprisonment, with the men dancing as if shackled, trying to climb up the walls of their cell to peer out into the world surrounding the prison, and being tested for venereal disease because of the sexual violence prevalent in the prisons. The play depicts and explores the violence that the men experience in prison—from the other inmates as well as the prison authorities—and illuminates the terrible conditions they all experienced because of racism. The play emphasizes the imprisonment of the men, both before and after their physical incarceration, because the apartheid laws oppressed and punished them unfairly.
