Squirm (1976) Timeline Explained – Every Event in Order

When the storm knocked down power lines into the mud, over 300,000 volts electrified the wet soil where worms lived. This voltage mutated the creatures into aggressive, man-eating predators that hunted at night. The electricity continued leaking into the ground even after the storm, keeping the worms dangerous throughout the night.

Foreshadowing: The diner scene established that dangerous voltage was still coursing through the ground.

Beardsley was killed and eaten by the electrified worms before the events of the main story. His skeleton was found in Roger Grimes' truck after the worm escape. Mick and Geri confirmed the skeleton was Beardsley by comparing the teeth with X-rays at a dentist's office.

Foreshadowing: Beardsley was last seen before the storm, when the worms were still normal.

Roger had been bitten multiple times by the electrified worms, which caused him to become deformed and lose his thumb. The worm bites appeared to have affected his mind, turning him violent. He kidnapped Geri and attacked Mick, likely because the worms had corrupted his behavior.

Foreshadowing: Roger showed Mick his bitten-off thumb and explained worms become deadly when electrified.

The worms were only active at night, drawn out by the electricity still conducting through the wet soil. When the power was restored to Fly Creek the next morning, the electrical current that had been leaking into the ground was properly grounded through the restored power system, causing the worms to retreat or become dormant.

Foreshadowing: Mick noticed the worms emerged at night when the ground was wet and conductive.

A violent electrical storm on September 29, 1975 knocked down power lines onto rain-soaked fields. The high voltage electrified the mud and mutated the native worms into aggressive, flesh-eating creatures. Additionally, 100,000 bloodworms and sandworms escaped from Roger's truck the next morning, spreading the infestation throughout town.

Foreshadowing: The opening scene established the storm and power line falling into the mud.

The worms entered homes by chewing through tree roots that connected to the houses. At Naomi's house, the worms gnawed through roots beneath the home and caused a tree to crash into the structure. The wet, electrically conductive soil allowed the worms to travel underground and emerge inside through foundations and walls.

Foreshadowing: The tree root chewing was heard during dinner before the crash.

No, Sheriff Reston was killed by the worms. During the town-wide attack, the sheriff and his date were eaten alive inside the jail cell. Earlier, he had dismissed Mick and Geri's warnings about the worm threat, failing to take action that might have saved lives.

Foreshadowing: The sheriff consistently ignored warnings about the dangerous worms throughout the film.

Naomi was killed during the worm attack on her house. When Mick regained consciousness after Roger abducted Geri, he discovered Naomi's remains covered in worms. She was one of the major characters who did not survive the night.

Foreshadowing: Mick warned everyone to stay indoors with candles to ward off the creatures.

The worms emerged primarily at night because the wet ground from the storm made the soil conductive. At night, the temperature drop and darkness coincided with the continued electrical leakage into the soil, making the conditions ideal for the mutated worms to hunt. They retreated or became dormant when the sun came up and the power was restored.

Foreshadowing: Mick observed the worms becoming active after dark throughout the film.

Mick and Geri survived by climbing a tree outside the house and waiting out the night. After defeating Roger by pushing him into a pile of worms and using a flashlight to defend themselves, they climbed up and remained in the tree until dawn. When morning came, the worms vanished and power was restored, allowing them to reunite with Alma.

Foreshadowing: Mick suggested staying indoors and using candles as protection earlier in the night.

Roger was repeatedly bitten by the electrified worms throughout the film. His thumb had already been bitten off before Mick noticed, and his body showed multiple wound marks. The bites appeared to cause physical deformation and likely infected him with whatever was causing the worms' aggressive behavior, leading to his violent transformation.

Foreshadowing: Roger showed Mick his bitten-off thumb and his body wounds on the boat.

The high voltage from the power lines mutated the worms, turning them into predatory creatures that hunted living flesh. The electricity essentially activated or created a killer instinct in the worms, transforming them from harmless soil dwellers into man-eating predators that attacked anyone in their territory.

Foreshadowing: The first worm attack occurred when Mick was bitten on the boat.

• cannibalism
• predation
• mutation
• attacking humans
• flesh eating
