Burt is arguing with Walter Chang about the ammo he special ordered for him and Heather. Earl Bassett and Valentine McKee grab a beer and tell Walter, Burt and Heather about Rhonda LeBeck's seismograph readings and Burt warns if Rhonda finds something then the Federal Government will come in and take over their land. Later, Mindy sees Valentine and Earl drive back into town and they park their truck in front of Walter's store. Mindy sees something latched onto Valentine and Earl's truck, and Burt uses a shovel to detach it and Walter haggles with Valentine and Earl for it. Burt tells the others he thinks there must be more somewhere. The residents of Perfection have a meeting and Burt suggests they arm themselves and Miguel comes up with the idea for two people to take Walter's horses and ride to Bixby. Burt and Heather come home from hunting for the Graboids and Heather sees everyone on their roofs. Burt calls Walter on the CB and Valentine tells him the Graboids are heading in his direction and to get on their roof. Heather and Burt arm themselves and a Graboid bursts its way into their basement. They manage to kill it with an elephant rifle and tell the others they killed it, and Valentine tells them there are still two more. The Graboid that originally attacked Valentine and Earl's truck starts to attack different buildings to test their structural integrity. Valentine calls Heather on the radio and tells her they have to leave together and before she and Burt can drive their truck to pick up the rest, a Graboid grabs it and destroys it.
Burt and Heather make pipe bombs and get into the trailer being pulled by a bulldozer with the others. They drive towards the mountains, but before they can reach them, the Graboids set a trap and dig a pit in the direction the bulldozer is heading, causing it to crash. Burt uses a pipe bomb to make the Graboids run away, but they come back again. They use another one to make them run away while they run towards a set of boulders. Burt tells Heather that if it comes to dying by the Graboids or starvation, he plans on letting them take him while he is holding a lit pipe bomb. Earl has the idea of attracting the Graboids and then feeding them a pipe bomb. They manage to kill one, but as they try it against the last one, it spits the pipe bomb back at them. Valentine, Earl and Rhonda are forced to run off the boulder and as they try to run back, the Graboid emerges in front of them. Valentine has the idea to use himself as bait and runs towards the edge of a mesa. Earl runs after him followed by Rhonda who hands Valentine a lighter to light the fuse on the last bomb. Valentine uses the bomb to make the Graboid run towards the edge of the mesa and it falls to its death.

Earl calls Burt and Burt tells him Heather is visiting her sister. Earl tells Burt about the Graboids in Mexico and asks for his help. Burt drives up in a Deuce and a Half and Earl introduces him to everyone. Burt shows them the equipment he got from the Mexican government and gives Earl and Grady Hoover elephant guns. Burt admits to Earl that Heather isn't coming back and then shows off the .50 caliber rifle he got. Earl and Grady and Burt then go their separate ways to hunt Graboids after Burt gives Earl and Grady some of his MRE's. Burt makes a recording noting he hasn't been in contact with anyone for hours and is heading to the main office and also hasn't had any sightings of Graboids lately. As he is stopped looking at his map, he is surrounded by a group of Shriekers. In the morning, Burt drives up in his truck and angrily tells Earl he was denied critical information. He then shows him the captive Shrieker he brought back and they put it in a cage. They test the ability of the Shrieker to detect them and realize it senses with thermal vision. Kate Riley then figures out they communicate by emitting heat. Grady feeds it part of an MRE and after it eats it, it vomits up another Shrieker. A Shrieker breaks into the office and Earl looks into the warehouse and sees a large group of Shriekers eating Burt's MRE's. Earl, Burt, Kate and Grady run towards a building, but it turns out to be only partially completed. They use doors to hide themselves while they walk towards Julio's car. A lone Shrieker is standing between them and Julio's car and Burt uses his .50 cal rifle to kill it. When they get to the car, they find out Burt's fired round penetrated the engine block. As they are running towards the cantina, a Shrieker senses them and shrieks. Earl and Kate make it into the cantina while Grady is forced to climb up an oil tower and Burt has to jump into the bucket of a front loader. Earl uses a heated up jumpsuit tied to a clothesline to distract the Shriekers while he and Kate climb up the oil tower Grady is on. While they are waiting to be rescued, Grady calls Earl and Kate over and they watch as the Shriekers start to form a pyramid to get to where they are at. Burt gets out of the bucket and runs towards another warehouse. The Shriekers all follow him and he runs out the backdoor and locks them inside. The Shriekers start to shriek and Earl, Kate, Grady and Burt realize the warehouse stores sweet snacks. Earl has an idea to spray himself with a fire extinguisher to block his heat signature while he goes into the warehouse and gets some of Burt's bombs which are inside. Earl tells everyone to run and Burt tells everyone to keep on running when he finds out Earl put the bomb in Burt's truck. The bomb explodes causing a giant depression in the ground and killing all of the Shriekers.
