Adventurous, trail-blazing Wolf lives in a northern mining town and spends her days exploring the mountains and wilderness with her three best friends Penny, Ann and Brandi. The girls' secret refuge is their tree-house hideaway, Birchwood, Wolf's favourite place on earth. When her beloved grandmother tells her that she is the great-granddaughter of a tree talker, Wolf knows that she is destined to protect the birch trees and wildlife that surround her. But Wolf's mother doesn't understand this connection at all. Not only is she reluctant to engage with their family's Indigenous roots, she seems suspiciously on the wrong side of the environmental protection efforts in their hometown.
