Echoes on the Ridge

An ecologist seeking solitude on a treacherous mountain trail witnesses an impossible event: a desperate hiker who vanishes into thin air, leaving no tracks. Teaming up with the trail's lone ranger, he discovers they've seen the ghost of a future tragedy. As the mountain's whispers grow louder, they must unravel its dark history to prevent a massacre foretold in an echo, before the mountain itself claims them too.
