A grieving young Claudia wants only one thing: to bring her mother back. She lights the candles, whispers the words and summons the beasts of death - ancient creatures who guard the door between the living and the dead. As the shadows part way, a creature steps forward from the darkness and invites her to play a dangerous game with only one lifeline.

In a small mining town, the local tycoon tells stories of a gold mine that could turn the whole town into a wealthy estate. Many locals volunteer, including Jose, an 18-year-old raising himself and his younger sister, Mercedes. The miners go down but succumb to an evil force deep within the mine, disappearing from the face of the Earth. The town quickly gives up hope, but Mercedes takes it upon herself to find her brother and the missing gold, no matter the costs. She'll have to take on the tycoon and perhaps even the Devil himself, but she will find out what happened deep down in The Devil's Vein.
