As Diego the bear is a social animal and needs the company of other bears, Jimmy and park director Stevie bring in Brunhilda from Romania. But the two bears argue - and no one wants a bear fight. And another polar bear called Hope joins Ewa, Flocke and Tala on the reserve.

Jimmy and the team build a vast bespoke enclosure when a pack of 12 arctic wolves need a new home. The hierarchy in the pack has recently changed, so Jimmy and his team need to plan the move meticulously to keep the balance of power stable. The pack arrives safely but on the first night one wolf rips open the top of the wolfhouse and gets out onto the roof. Soon, however, the wolves are out and about exploring their new reserve with its pools and woodlands and also welcome four new pups to their pack. Ewa the polar bear is joined by two other homeless bears - Flocke and Tala.

The farmer and conservationist tries to relocate two polar bears from Sweden to his wildlife park in Suffolk, after the park they lived in was shut down. They can't be released into the wild as they've only ever lived in captivity and wouldn't survive. Jimmy and his team build Europe's largest polar bear reserve, while the polar bears' journey from Sweden goes well - until disaster strikes.
