In a rural Appalachian coal mining town, nine miners—already struggling with dangerous conditions and dwindling resources—descend into the depths for a routine shift. But when a methane explosion traps them miles beneath the surface, they are left with only one hour of oxygen and little hope of rescue. Tensions rise, past conflicts surface, and survival becomes a test of will, sacrifice, and unity. Mine 9 is a gripping, claustrophobic drama that exposes the human cost of coal mining and the strength of the Appalachian spirit in the face of tragedy.
