"Wow!" gasped Ben. "A secret organisation - and Uncle Stephen wants us to join. We'd better get packed."
Twins Ben and Zoe receive a mysterious message. Could it really be from Dr Stephen Fisher, the famous zoologist who has been missing for years? Dr Fisher needs their help. Will they join Wild, the secret organisation he set up to save animals in danger? And are they ready for their first mission - to rescue a tiger and her cubs from an evil gang of poachers? You bet!
Ben and Zoe's mission takes them to a reservation in the remotest jungles of Borneo, where ruthless loggers have frightened a young orang-utan away from his safe home. But it's not just the young orang-utan who's in danger. Someone has their eye of the reservation's precious rainforest land and it seems they'll stop at nothing to get it.
Ben and Zoe are at a game reserve in Kenya's vast savannah, where some tourists are paying big money to illegally hunt elephants for 'sport'. The latest visitor has his sights set on a baby elephant and its mother. The race is on for Ben and Zoe to reach the vulnerable elephants, but will they get there in time?
Ben and Zoe are off to the Caribbean, following reports that an unscrupulous marine park has dumped a young dolphin into the ocean. Because the dolphin was born in captivity, he is unprepared for life in the open sea. It's up to Ben and Zoe to guide the defenceless dolphin to safety, before he finds himself in dangerous waters.
The children's skills are put to the test when they are sent to the mighty Himalayas, where a snow leopard and her cub have been cut off from their territory by an avalanche. Meanwhile the snow leopard's other two cubs have been left to fend for themselves. Can Ben and Zoe survive the sub-zero temperatures and dangerous terrain, and lead the mother and her cub home to her family?
Ben and Zoe travel to the Kalahari Desert, where a lion cub has fallen down a well, and it's up to the children to rescue it. With some cool new gadgets, including a wind and solar-powered dune buggy, they set off. But with the thirst-beating heat and deadly creatures at every turn, as well as a powerful sandstorm to contend with, will they manage to rescue the cub and return it to its pride before it's too late?
