A unique short 21-minute documentary directed by Sohan. It is based on the background of Mullaperiyar dam which is a masonry gravity dam on the periyar river in Kerala. The documentary discusses The Banqiao dam (492 million cubic meter) in China which was destroyed by torrential rains in 1975 and claimed the lives of 250,000 people. Mullaperiyar dam has similar capacity and Roy gives a scientific explanation about the disastrous nature of the dam and how a natural disaster can affect lives of many.

The documentary suggests that 85% of all large dams (40,000 across the globe) will pass their projected life spans by 2020. The total number of dams and hazardous dams, both are increasing at an alarming rate. Natural disasters like torrential rains, floods, earthquakes and landslides can damage the dam. Also, untimely rains and floods have increased lately, as a result of global warming. Notwithstand-
ing the disasterous nature of dams, no checks and balances are being made to ensure safety in case of natural disasters, which can lead to dam collapse.
