A report on Kodinhi, India, noted for producing an unusually high number of twins. It has Doctor's baffled and scientists searching for a common denominator that may hold the key to infertility issues so many around the world are facing.
The host of the program is being driven around by his interpreter who also happens to be a twin himself and is the father of twins too. And it's not just the people having twins, the livestock have joined in on this unexplained peculiarity and are also giving birth to twins.
It was a truly fascinating documentary that I watched on Netflix some time ago. I can't believe so much data is missing on the imdb entry for it.
