Game wardens at Periyar Wildlife Sanctuary in South India are horror-stricken when they discover dead female elephants littering the once peaceful 350-square-mile block of land.

Local conservationists are forced to become investigators, but they are running out of possible explanations for these mystifying deaths. Can they track down who or what is killing these gentle giants?
