In director Darius Mackenzie’s feature debut, a writer looking for inspiration for her next project takes a canoe trip with her boyfriend through the backcountry of Oregon. In this area known for its fossil record stretching back roughly sixty million years, the earth holds the imprint of worlds now gone and time seems to widen with every bend of the river. When she disappears one night, time is laid bare, with nature revealing itself for what it truly is: equally uncaring and awe-inspiring.
