Tremors 2: Aftershocks is a 1996 direct-to-video sequel to the comedy horror film Tremors. In this sequel, the character of Earl Bassett, returning from the first film, is hired to deal with a subterranean "graboid" infestation at a Mexican oilfield. It was directed by S. S. Wilson, and stars Fred Ward, Christopher Gartin, Michael Gross, and Helen Shaver.
After spending all the reward money from his first encounter with Graboids, Earl Bassett agrees to hunt more of the deadly creatures at a Mexican oil refinery for $50,000 each. Knowing that he cannot face the monsters alone, Earl recruits Burt Gummer, another veteran of the incident in Nevada, to supply the firepower. There is only one problem: the Graboids have now evolved into creatures able to attack above ground.
Reviews for the film were mostly positive, with some critics labeling it one of the best direct-to-video sequels ever made.
The film is the second in the Tremors franchise. It was followed by a 2001 sequel, Tremors 3: Back to Perfection.
Plot
Years after the events of the first film, Val McKee has moved away and married Rhonda LeBeck, while Earl Basset has squandered his fortune on a failing ostrich ranch. He is approached by Carlos Ortega, who informs him that Graboids are killing his workers at his oil field in Chiapas, Mexico, and hires him to hunt them down. Earl initially declines, but Ortega's taxi driver, Grady Hoover, convinces Earl to change his mind after mentioning that Ortega will pay $50,000 for each Graboid killed; both join the hunt. Upon arrival, Earl learns that the company would pay him double if he caught one of the creatures alive. He also meets geologist Kate Reilly, her assistant Julio, and a mechanic named Pedro, all of whom are scientifically investigating the Graboids.
Earl and Grady begin systematically killing the Graboids by using remote-controlled cars rigged with explosives. Though their strategy seems to work, the vast number of Graboids overwhelms them and Earl enlists the help of Burt Gummer, who arrives with a "deuce-and-a-half" truck loaded with firearms and explosives. The next day, Earl and Grady are surprised by one of the Graboids, causing them to drive backwards in a panic and crash the truck into an inclined ditch. Returning to where they saw the Graboid, Earl and Grady find that the creature looks sick and non-aggressive with all of its tentacles mysteriously dead. Realizing they have one of the creatures alive (which Ortega offered $100,000 if accomplished), they call Pedro to come and pick them up along with the Graboid. However, the Graboid later begins making horrific and painful sounds and is soon found dead with a huge hole torn open into its body. They see Pedro's truck approach from the distance but it suddenly stops, prompting Grady and Earl to investigate and discover the truck’s destroyed engine as well as Pedro’s remains. They make their way to a nearby radio broadcasting building which has similarly been destroyed, only to be met by strange bipedal graboid-like creatures. Earl successfully kills one as it charges him, but the two flee in a car they had found as more of the creatures arrive. Meanwhile, Burt's truck is ambushed by a pack of these new creatures while returning to base.
The following morning, the creatures have made their way to the oil refinery, where Julio is violently killed by one. Grady and Earl arrive before it can attack Kate, with Burt shortly arriving thereafter following a near-fatal firefight that has left him drained of ammunition. Through experimentation, the group discovers that these creatures (now dubbed 'Shriekers') are hermaphrodites that can replicate at an incredible rate after eating enough food. They also learn that the creatures cannot hear unlike their predecessors, but rather see heat through special infrared receptors on their heads. However, they are attacked by the Shriekers, who have discovered Burt's MRE food supply and have rapidly doubled their numbers in a matter of minutes. They run for Julio's car, but Burt accidentally disables it while killing a Shrieker.
