When one of journalist Rajkumar Keswani's friends dies at the Union Carbide plant after exposure to toxic gas, he decides to investigate. Local government officials dismiss him, but safety reports smuggled to him open his eyes to the potential for disaster. Rajkumar Keswani wrote his first article 40 years ago, warning of the dangers posed by safety lapses and poor maintenance at the chemical plant. During a dogged investigation pitting him against political power, corporate money and the indifference of the media and public opinion, he never gave up. This cinematic documentary - narrated by Narinder Samra and featuring key witnesses - tells Keswani's courageous story for the first time. Producer: Neil McCarthy (Death in Ice Valley podcast)
