A short clip of a woman sitting side-ways in a small, wooden boat that is sailing on still waters through a majestic canyon. As the boat comes around a wall of the canyon covered in trees, the sun shines on the woman in the boat and the scene opens up to show even more faces of the canyon covered in plants and trees.
