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.
