That evening, with zero sign of their friends, a massive feast is laid on by the mine’s cantankerous Captain, who performs a long speech encouraging all to indulge as this is to be the workers’ last night before returning to their families. With good reason for suspicion the protagonists feign gluttony and consume as little as humanly possible. Unfortunately, as they later find, even that’s not quite enough. Night falls, they hide and as the workers fall comatose, the wardens, overseen by the Captain, make preparations to pump their poisoned stomachs. It turns out the purpose of the mine is to procure an excess of human stomach acid used in the production of a bastardized blood red wine, sold and loved in the region.
After the wider conspiracy is revealed and upon realizing their friends must be long gone, the partners decide they must destroy the facility. A spanner plugs the works however, as one of the men experiences mild effects of the poison and the production of acid in his stomach goes into overdrive. As his chest literally bubbles he says what may be his final goodbyes to his partner and the other man is left to do the heavy lifting alone.
He succeeds and as they flee, arm in arm, the demon Captain erupts from the burning embers and curses the two men to the hell of crippling acid reflux for the rest of their days. They see no reason to worry though, as they’re sure to return home hailed as heroes.
