After a near-fatal 1995 motorcycle collision, Dan Haggerty (The Life and Times of Grizzly Adams) made his comeback with this time-travel tale. A Portland, Oregon, family on a camping trip arrives at a mountain where young Dylan (Dylan Haggerty) and his sister Nicole (Nicole Lund) explore a cave, get zapped 127 years into the past, and meet mountain man Jeremiah (Dan Haggerty), who offers to help locate their parents. However, developer Boss Man Burt plans to dynamite the mountain to bring the railroad to a nearby town. Jeremiah, the kids, animals, and local Indians all join forces to outwit Burt's villainous henchmen. Filmed at Crater Lake and Oregon mountains. The character named Jeremiah is a reference to Vardis Fisher's historical novel Mountain Man (1965), filmed by Sydney Pollack as Jeremiah Johnson (1972).
