When siblings Mae and Patrick Alridge return to their late grandfather’s farm to settle his estate, they stumble upon an old, rusted silo — sealed shut and whispered about in family lore. Despite warnings in their grandfather’s journal and strange symbols carved into the barn walls, Patrick insists on opening the silo. What they find inside changes everything. Inside is not just rot and rust, but something alive — or something pretending to be. A third presence makes itself known: The Watcher, a voice that speaks only in whispers and seems tied to the land itself. As night falls and strange phenomena begin, the siblings realize the farm wasn’t abandoned — it was quarantined.
