This prequel of the bone-chilling Tremors begins in the town of Rejection, Nev., in 1889, where 17 men die under mysterious circumstances. Spooked by recent events, the miners who populate the town leave in droves until there’s nothing left but a shell of a community. It’s up to the remaining residents to get to the bottom of the deaths — but they must do so before they, too, are eradicated off the face of the planet.

Burt Gummer (Michael Gross) and his son Travis Welker (Jamie Kennedy) find themselves up to their ears in Graboids and Ass-Blasters when they head to Canada to investigate a series of deadly giant-worm attacks. Arriving at a remote research facility in the artic tundra, Burt begins to suspect that Graboids are secretly being weaponized, but before he can prove his theory, he is sidelined by Graboid venom. With just 48 hours to live, the only hope is to create an antidote from fresh venom — but to do that, someone will have to figure out how to milk a Graboid!
