Tremors 4: The Legend Begins

Water from a nearby hot spring seeped into the silver mine area and triggered the hatching of graboid eggs that had been dormant underground. This caused the juvenile graboids to emerge and attack the miners, resulting in 17 deaths.

Hiram was inexperienced with and did not like firearms. As the mine owner who had likely never faced frontier dangers, he recognized he lacked the skills to defend against the creature attacks and needed professional help.

Kelly was eaten alive by a fully grown graboid that emerged during the attacks. Despite his reputation as a gunfighter, the creature overwhelmed him while the group was fighting multiple graboids.

Earlier in the film, Kelly teaches Hiram about firearms and life, making his death more impactful.

The residents refused because their livelihoods depended on the silver mine, and they would not abandon their homes. They also threatened to alert potential buyers to the graboid danger if Hiram tried to sell the mine out from under them.

While in Carson City, Hiram received a telegram warning that the fully grown graboids had made it through the pass and were headed toward the town. Realizing the danger was coming regardless, he used his remaining valuables to buy weapons and returned to lead the defense.

Hiram lured the adaptive graboid to the surface and attached it by the tail to the flywheel of a steam traction engine. He reeled the creature in and slammed it against the front wheels and boiler, decapitating it explosively on impact.

The earlier trap failures foreshadowed that conventional methods wouldn't work, requiring an improvised solution.

The townspeople agreed to keep the graboids secret because they feared that if word got out about the dangerous creatures, no one would ever settle in the area. They chose to use the mine's proceeds to pay for their belongings instead.

After the victory over the graboids, Hiram settled in Rejection, which was renamed Perfection. He built his home in the exact location where his great-grandson Burt's house would later stand, establishing the generational Gummer connection to the town.

After two graboids were killed by the town's traps, the third and final graboid adapted and learned to avoid all of the defensive measures. This forced Hiram to devise a new, improvised method using the steam engine to defeat it.

The town was renamed from Rejection to Perfection after the graboid threat was eliminated. The new name reflected a fresh start for the community, though the film does not explicitly explain the naming choice beyond symbolizing the town's survival and new beginning.

A total of four graboids hatched from the eggs. Juan Pedilla had already killed one with a pickaxe before the group discovered the full number, meaning three remained active throughout the attacks.

At the film's conclusion, Hiram was given a Colt 1865 Gatling gun, symbolizing his transformation from a firearms-averse mine owner to an armed defender. He began target practice and embraced weaponry, foreshadowing the gun-loving survivalist legacy that his great-grandson Burt would later embody.
