This six-part British drama series tells the story of real-life wildlife enthusiast George Mottershead, who in the early 20th century, set out to create a new zoo, one in which the animals would not be confined to cages. In 1931, his dream would be realised with the opening of the Chester Zoo, which to this day remains the most visited wildlife attraction in Britain and is rated one of the world’s best zoos. Tonight, George (Lee Ingleby, right) tries to rescue to Himalayan black bears from a cave. Meanwhile, Reverend Webb (Stephen Campbell Moore) is determined to find out what the Mottersheads are up to.
