Veteran coal miner George Marsh (Jeff Fahey, Planet Terror) is about to retire, and he's giving his daughter Samantha a tour of the mine on his last day. Six-hundred feet below the surface, a catastrophic collapse traps them and a crew of miners, leaving them with 72 hours before rescue workers arrive. But the drill strike that caused the disaster also opens a hole into an unknown chamber, and before long the crew suspects they might not be alone. With their oxygen supply steadily depleting, George and Samantha must figure out a way to stay alive as resources become scarce and the danger rises. Inspired by true events, Beneath is a claustrophobic, bleak, and terrifying look at humanity in its deepest, darkest places.
