On an Earth with titanic forests instead of oceans, highly-trained rangers brave the depths to bring back footage of treacherous landscapes and ferocious beasts. It's a dangerous job, but it has its moments: when a trio of ranger recruits stumble across a strange artifact, they begin to unravel a mystery with planet-spanning ramifications. The only problem is, if they're going to uncover the truth, they have to survive the worst the forest can throw at them first.
