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!
A graboid eats three people in the beginning of the movie, while there are sled dogs close by. The dogs run off safely and are not pursued by the graboid.
There are dogs in the beginning, but they run off before the Graboids attack. The monsters in this movie are technically precambrian animals, and four of them die throughout the movie, but they are killed in self-defense.
