chunk: After the people return to town, the Graboids attack, eventually killing general store owner Walter Chang and forcing the other citizens to the town's rooftops. Meanwhile, nearby survivalist couple Burt and Heather Gummer manage to kill another one of the creatures after unknowingly luring it from town to their basement armory. In town, the two remaining Graboids attack the building foundations, knocking over the trailer of a citizen named Nestor and dragging him under. Realizing they cannot stay any longer, Val commandeers a bulldozer and chains a partial truck trailer to the rear, while everyone else distracts the creatures; the survivors use it to try and escape to a nearby mountain range. On the way there, both Graboids create an underground sinkhole trap that disables the bulldozer, forcing the survivors to flee to the safety of large boulders.
