Eleven-year-old Emily (Kaitlyn Burke) is an environmental activist in training, having saved a bear cub wounded by poachers and nursed it back to health . When Emily's 16-year-old sister Melissa (Kimberley Warnat) -- another would-be environmentalist -- and her high school pal Daniel (Kristian Ayre) go to the woods to document evidence of a shady millionaire's (Alan Thicke) clear-cutting operation, Emily follows her and promptly gets washed away down a fast-flowing woodland river. Soon everyone is looking for the lost girl, including Melissa and Scott (Eric Johnson), a hunky slice of logger beefcake. With only the trusty bear cub -- now grown into a 700-pound adult named Masha -- as her guide, Emily struggles to make it out of the woods alive. ~ Rebecca Flint Marx, Rovi
