This is quite frankly one of the most edgy and gritty documentaries I have seen. Itâ€™s a little old, but the issue it talks about is still as relevant today as it was then. It talks about Indiaâ€™s sewer cleaners, a disorganized workforce consisting of so called â€œlower castes,â€ who work in hazardous conditions for a meager salary to ensure that society remains clean and hygienic. The message at the end of the video will leave you in thought. Be warned. A lot of scenes in this video will could make your stomach turn.
