Polar Meltdown

Following reports of a polar bear found dead near an Alaskan village, Dr Fisher is sending Ben and Zoe, Wild's number one operatives, to investigate. It's highly unusual for a polar bear to come so close to human habitation and this suggests something is seriously wrong. But the twins' mission takes another turn when they discover that the dead bear had recently given birth. This means there is an orphaned cub out there. Will Ben and Zoe find it in time?
