When Joe and Aesha's mother is given an assignment to train young vets, the Brook family visits an important nature reserve near Lazovsky in eastern Russia. In this spectacular snow-bound landscape, Joe is thrilled by the prospect of glimpsing a rare Amur tiger in the wild.

However, the tigers prove elusive - until Joe's interest in wildlife photography leads him to make an unexpected discovery that puts his life in danger.
