In a small, remote mountain town, an old silver mine, long abandoned following a series of tragic accidents, is being reopened. The mines have remained untouched for nearly a century, shrouded in mystery and local superstition. Two young men, Mark and Roger, arrive with the task of getting the mine operational. They are joined by their girlfriends, Jessica and Trish, who are looking forward to a relaxing retreat in the nearby cabin they've rented. As the couples settle in and the work on the mine begins, the townsfolk express unease, hinting at a dark past and warning of bad omens.

The group pays little mind to the town's legends, focusing instead on exploring their new surroundings and planning for their futures. However, strange occurrences start to plague them: odd noises echo from the depths of the mine, pets and wildlife are found dead, and one by one, people start disappearing. The revitalization of the mine has awakened something sinister that has lain dormant underground. As terror creeps from the shadows, it becomes clear that the mine's secrets are far more malignant than mere superstition, and the group must confront the unknown as dread escalates with each passing night.
