In the ruins of a destroyed world, two survivors discover a mysterious, moss-covered refuge where hope and fear meet.
After the apocalypse, the few survivors fight not only against the merciless violence of nature, but also against loneliness and dwindling hope. In the midst of an endless storm, Paul and Hannah find refuge in an abandoned research laboratory. While Paul searches the place for supplies, Hannah is drawn to a strange discovery: a dense carpet of moss has overgrown the entire laboratory and seems to radiate an eerie vitality. But the deeper the two delve into the mystery of the moss, the clearer it becomes that they are faced with an all-altering decision that could mean the end of their journey.
