True Heart (1999)

Twin brother and sister Sam (Zachery Ty Bryan) and Bonnie (Kirsten Dunst), who argue frequently, become stranded after surviving a horrific plane crash in the Canadian wilderness. While struggling through the forest, they meet a wily Native North American named Khonanesta (August Schellenberg), who agrees to help them reunite with their family. As the trio traverses the treacherous wood, they strive to elude poachers who wish to hunt Khonanesta's adored Kodiak bear companion.
