Briar and Bramble, who lost their mother Barbara when they were cubs, are thrown into danger when escorting a scientist, which may lead them to a family reunion.
Bear brothers Briar and Bramble set off on an adventure with their human friend Vick to Wild Land, an amusement park where humans can turn into animals using a gene-technology bracelet.
A strange yet familiar creature turns up, prompting a flooding of Bramble Bear's youthful memories. The forest descends into turmoil when a group of strangers arrive, on the hunt for the mysterious creature.
Bramble, Briar, and Vick unexpectedly follow a time traveller 100 years in the future, where they find Earth beset by environmental catastrophe, with humanity barely able to survive.
