There’s something else at Big Thunder too, something otherworldly. Local legend holds that the mountain has been cursed by the Shoshone since a notorious mining accident at this western outpost some 30 years ago.
About as far from the splendor of the wild west as one can get, widower Dr. Gavin Kelly (Ed MacLiam) lives with his 17 year old daughter Lizzie (Ruth Bradley) and young son Jack (Pierce Gagnon) on the crowded lower east side of Manhattan. Son Jack suffers from a frightening respiratory illness for which Gavin Kelly strives to find a cure.
The family’s life will suddenly change when Gavin gets an offer to move to the mining town of Big Thunder because they need a doctor and are willing to pay any price. Lured by the promise of a better life, the Carsons Kelly’s, accompanied by their nanny Nora (Spencer Locke), set out on a frontier adventure and meet the mysterious benefactor who brought them there: Abel White (Alex Hassell). But there is something about this Eden on the edge of civilization and something about Abel White–supernatural forces are at work and their son seems to be a conduit. Together the family will uncover the mysteries, dangers and unspoken secrets of the haunted mountain: Big thunder
