The film was released in 1971.
It is about the directors of the film time-travelling to the deep southern pre-Civil War American South.
There, they attempt to document every distressing, graphic and unbridled detail of the slave's lifestyle.
Some scandalous scenes that stood out in this film included:
the directors attending a social event where the guests threw their food scraps to half-naked Black children crammed underneath the dining table; the slave-ship arriving from Africa and the slavers discussing the people like livestock; the slave training camp, which resembled a factory-line; and the scientist that was looking to support his thesis of White people being inherently superior
