Tremors 2: Aftershocks

Carlos Ortega hires Earl Basset after learning Graboids are killing workers at his Chiapas oil field. Earl initially declines the job, but Grady Hoover convinces him with the promise of big pay per creature. Earl agrees to join the expedition to eliminate the threat.

Earl learns the company would pay more if a Graboid could be captured alive. He meets geologist Kate Reilly, her assistant Julio, and mechanic Pedro who are scientifically investigating the creatures. The team travels to the oil field to begin the hunt.

Earl and Grady start systematically killing Graboids using remote controlled cars rigged with explosives. Their tactic initially works, but the huge number of Graboids soon overwhelms them. They realize the danger is far from over.

Earl decides to bring in Burt Gummer, hoping for his heavy firepower. Burt arrives with a deuce-and-a-half truck packed with firearms and explosives, ready for a full scale assault. The team grows larger and more determined to stop the creatures.

The Graboid that attacked them looks sick as tentacles die and the group believes they might have captured one. They call Pedro to come pick them up with the creature. Pedro's truck arrives but its engine is destroyed and Pedro's remains are found nearby, signaling a darker danger.

The group returns to the area and finds a destroyed radio broadcasting building. They are confronted by strange upright, bipedal graboid-like creatures. Earl kills one as it charges, and the others flee in a car as more of these creatures converge.

A pack of the evolved creatures ambush Burt's truck as it returns to base. The team fights to defend themselves while the threat grows, underscoring the escalating danger of the swarm.

The Shriekers arrive at the oil refinery and attack. Julio is violently killed by one, while Grady and Earl reach to defend Kate. Burt soon arrives after a near fatal firefight that leaves him drained of ammunition.

The survivors learn that Shriekers are hermaphrodites capable of rapid reproduction after feasting. They do not hear but instead see heat using infrared receptors on their heads. The swarm continues to multiply as they feed on available food sources.

The Shriekers multiply and pursue the group. Burt is trapped in a bulldozer bucket as the others attempt to stay ahead by anchoring themselves on an oil tower. The team recognizes they are running out of conventional options.

Seeking a way to contain the swarm, they discover rice flour stored nearby and use it to feed and trap Shriekers inside a storage shed. Earl uses CO2 from a fire extinguisher to mask his body heat while he searches for Burt's explosives. He places the detonator among Burt's supplies before making an escape.

A massive explosion detonates, wiping out the Shriekers and destroying the refinery complex. In the aftermath, Earl and Kate decide to pursue a romance while Grady hints at opening a monster themed park funded by Ortega's debt. The threat is ended, but the monster world of Chiapas has changed forever.
