After gaining magical powers from Nian, the legendary Year Monster, our heroes are transported to a magical realm to stop a world-ending crisis. Briar deals with losing his 'big brother' status after the others gain powers, leading him to stumble into a plot that threatens both the human and immortal worlds.

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.

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.
