It's their first week in Africa, and Mandy and James are hoping to see Leela, a leopard raised by big cat expert Sandie Howard and now released into the wild. Leela has recently had cubs, so when her tracking device goes out of range, everyone is concerned. Then Leela is found drugged and alone. What has happened to her cubs? Can Mandy and James reunite them with their mother before it's too late?
