Tremors 4: The Legend Begins

In the mining town of Rejection, Nevada in 1889, an unseen menace has begun terrorizing the inhabitants and eating up the mining resources, and therefore the profits, of mines owned by one Hiram Gummer, great-grandfather to future monster-hunter Burt Gummer. When Hiram brings in a mercenary to stop the deadly creatures, an all-out fight to the finish takes place across the streets of Rejection and underground in the dark mines.
