Kate walks up to Burt Gummer, Grady Hoover and Senor Ortega and is introduced to Earl and Grady by Senor Ortega who then leaves. Julio drives up and Kate introduces him to Earl and Grady and Julio comments that Earl must have made a lot of money on royalties. Later, Kate tells Earl that six people were killed and she shows him some maps with the locations of where the workers were killed. While looking at a fossil, Kate realizes it is a fossilized Graboid spike. By aging the rock, she comes up with the idea that the Graboids existed from before the Cambrian Era. Pedro calls everyone over to look at the monitor and Julio points out a large object coming their way. Burt Gummer 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. Later, Earl calls Kate and asks her to send Pedro to come and pick them up. In the morning, Kate and Julio try to figure out why they can't reach anyone and Julio is suddenly attacked and killed by a Shrieker. Earl and Grady arrive and help Kate and tell her the Graboids have changed and Pedro is dead. As they are trying to leave, their car is destroyed by a Shrieker. 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 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, Kate tells Earl what brought her to Mexico and Earl asks her out on a date. Kate tells Earl about how she used to model while going to college and Earl recognizes her as the model from the centerfold he had hanging in his trailer. 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. The foam from the fire extinguisher starts to wear off and Earl manages to set the timer on a bomb and climb out of the building using a fire hose. 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. Earl asks out Kate again and she accepts.
