In the shadowed valleys of Guanajuato, an abandoned mine bears the weight of an ancient curse that has lingered for generations. The walls of the shaft are etched with forgotten rites, and the very air seems to hum with a malevolent presence that has kept locals at a respectful distance. When a British mining company decides to reopen the tunnel, the atmosphere shifts from historic curiosity to a palpable sense of foreboding, as the legend of the hand‑wielding demon begins to stir beneath the earth.

​Mark Baines arrives with the confidence of a modern entrepreneur, determined to prove that the old superstitions are nothing more than folklore. His wife, ​Jennifer Baines, follows him with a mixture of concern and resolve, eager to witness the venture that has drawn her husband away from home. The couple’s dynamic—Mark’s pragmatic optimism clashing with Jennifer’s cautious intuition—creates a fragile partnership that is tested the moment they step into the darkened tunnels, where the miners themselves refuse to go.

The mine’s hidden horror is whispered to reside in the left hand of those who dare enter, a cursed appendage that seems to awaken an inner darkness, urging its bearer toward unseen, wicked impulses. As the Baineses venture deeper, the oppressive silence is broken only by the faint echo of unseen forces, turning the cavern into a pressure cooker of dread. The film’s tone is relentlessly eerie, blending claustrophobic suspense with a creeping supernatural menace that promises to challenge every belief the couple holds about rationality, faith, and the unseen powers that linger beneath the surface.
