In August 2009, a thirty-nine-year-old policewoman went missing in Tamil Nadu. A month later, her heavily decomposed body was discovered in a drain by a graveyard. She had been brutally violated and killed. As the investigation started, the police detected a pattern in more than a dozen unsolved rape-and-murder cases with mutilated bodies of women turning up in graveyards, drains and empty fields along the highways. It didn’t take the police too long to find out that the perpetrator was a trucker named M Jaishankar. What followed was a cat-and-mouse game across states, many more gruesome killings, one of the most sensational jailbreaks in the history of the country, and a controversial suicide in a high security cell. The Highway Murders is the breathtaking true story of 'Psycho Shankar', one of India's most notorious serial killers, and one policeman's relentless decade-long battle against the 'terror of the highways'.
