Tom and Sophie join their mum in a dash to Whipsnade Zoo to help an elephant deliver its calf, and another exciting adventure begins. At first the elephant calf, Dirshani, struggles to survive as it doesn't eat well. With expert help and lots of care, the calf grows stronger, and Tom and Sophie have a new animal friend.

During the next year the young elephant is encouraged to take its place in the herd. Tom and Sophie dream that one day Dirshani will take part in the elephant demonstration. But there are a few hurdles for them all to cross before that dream is realised in this thrilling animal adventure.
