What Is Laserblast About?

The premise of Laserblast in 326 words, with nothing given away. The full story follows below.

In the relentless heat of the California desert, a small town clings to the rhythms of summer, its streets buzzing with the ordinary worries of a community far from any grand spectacle. The landscape is vast and empty, offering both refuge and exposure, a place where a restless adolescent can feel the weight of the world pressing in even as the horizon stretches endlessly. It is here that Billy Duncan drifts through a life marked by teasing classmates, a mother whose attention is pulled elsewhere, and the quiet expectation of becoming something more than a target of jokes.

Billy’s world is populated by a handful of people who shape his daily reality. His girlfriend, Kathy Farley, offers a glimpse of affection and normalcy, while her grandfather, Colonel Farley, a grizzled veteran with a taste for conspiracy, warns him to stay away from trouble. The town’s social hierarchy is underscored by a bully named Chuck, a circle of loyal friends, and the occasional meddling of local law enforcement, all of which create a backdrop of tension that mirrors the inner turbulence of a teenager yearning for purpose.

One blistering afternoon, while wandering the dunes, Billy discovers an odd, otherworldly object—a sleek laser rifle paired with a curious pendant. The moment he touches it, a surge of unimaginable power hints at possibilities far beyond the town’s ordinary limits. Unseen forces, hinted at by the brief appearance of alien figures in the desert, become aware of the weapon’s sudden reappearance, suggesting that the artifact is far from lost and that its reclamation will draw attention from beyond Earth.

The film balances the high‑school coming‑of‑age vibe with pulsing science‑fiction intrigue, casting the desert as both a playground and a hunting ground. As Billy grapples with the temptation of newfound ability, the story teeters between teenage rebellion and an escalating, unseen chase, promising a blend of personal discovery and alien mystery that keeps the audience poised on the edge of anticipation.

The complete story of Laserblast, from the first scene to the last, in 642 words (about 3 minutes). Spoilers throughout. Names in the text link to 4 cast member pages.

Spoilers ahead

In a sunbaked desert, a green-skinned figure wanders with a mysterious laser cannon strapped to his arm, and two reptilian aliens aboard an approaching spacecraft step out brandishing weapons. After a tense firefight, the aliens disintegrate the man and, once they spot an airplane in the sky, they retreat to their ship, leaving behind the cannon and a pendant the man wore.

Back in town, Billy Duncan, Kim Milford, wakes up to a morning that quickly sours: his mother has been invited to a trip to Acapulco and, despite his protests, she leaves him behind. He seeks out his girlfriend Kathy Farley, but her grandfather, Colonel Farley, Keenan Wynn, is a grizzled, conspiracy-spouting veteran who warns Billy to stay away. The teen world around him feels heavy and judgmental, with a bully named Chuck Boran, his friend Froggy, and a pair of sheriff deputies harassing him and giving him a speeding ticket.

In the desolate heat, Billy stumbles across something unbelievable: a laser cannon nestled with a strange pendant. He learns he can wield the weapon only while wearing the pendant, so he experiments, firing at things around the desert and letting his fear and excitement drive reckless bursts of firepower. At the same time, the alien crew on their ship converse in an unsubtitled language, and their leader orders them to return to Earth to recover the cannon they left behind. The tension between the human and alien sides begins to braid together as the town’s quiet routine starts to crack.

A pool party becomes a flashpoint. Chuck makes unwanted advances on Kathy, and Billy steps in to defend her, sparking a confrontation with Chuck and Froggy. That same night, Billy uses the cannon to explode Chuck’s car, an act that leaves the teens shaken and the authorities curious. Enter Tony Craig, a government official who arrives to investigate both the explosion and the broader desert mystery; he warns the sheriff that information about what happened must stay contained, suggesting a cover-up in the works.

Billy’s body begins to change, producing an unusual growth on his chest. Kathy urges him to see Doctor Mellon, and Roddy McDowall surgically removes a metallic disc from Billy’s sternum and arranges for it to be evaluated at the police laboratory. That night, a green-skinned Billy — now visibly deranged and threatening — attacks Mellon’s car and kills him in a fiery explosion. The next day, Tony investigates the wreckage and brings back a sample of unfamiliar material, which Mike London, Rick Walters, tests and identifies as inorganic and not of Earthly origin.

The violence intensifies as Billy, under the growing influence of the pendant and the cannon, kills two sheriff deputies who previously taunted him. He and Kathy share a night together in the aftermath, and when Kathy discovers the alien pendant, she cautiously places it on Billy’s chest. The result is a shocking transformation: his skin turns green, his face deforms, and a full-blown rampage ensues, with Billy firing indiscriminately with the deadly weapon. A small law-enforcement plane opens fire, but Billy destroys it. He continues to target Chuck and Froggy, obliterating their car in a blaze of laser power.

Tony Craig keeps pressing Colonel Farley for information as the two aliens land on Earth and join the hunt for Billy, moving through the landscape in a hastily stolen hippie van. They kill a passerby and commandeer his vehicle, while Billy roams an empty city block, firing at will. Kathy and Tony finally corner him in an alley just as one alien fires a beam from a rooftop, striking Billy down. The laser cannon and the pendant are destroyed in the aftermath, and the aliens depart aboard their spacecraft. Kathy collapses in tears over Billy’s corpse, while Tony looks on, left to reckon with the planet’s violent collision of human fear and otherworldly power.

Where and When Is Laserblast Set?

Laserblast is set in Desert and Small Town (Late 1970s). Here is why the time and place matter to the story.

When

Late 1970s

The events carry a late 1970s American vibe, with teens, a rural-desert environment, and a backdrop of governmental curiosity and conspiracy talk. The era’s casual social scenes juxtapose with sudden sci-fi terror, creating a sense of ordinary life spiraling into chaos. The technology and attitudes hint at a pre-digital, hands-on era of investigation and suspicion.

Themes

What Are the Themes of Laserblast?

3 ideas the story keeps returning to, among them Alien Influence, Transformation and Secrecy & Control.

  1. 01

    Alien Influence

    Alien technology intrudes into ordinary life, granting power and triggering violent acts. The pendant and laser cannon become catalysts that draw human actions into a destructive orbit around supernatural forces. The narrative explores how external, incomprehensible forces can destabilize relationships and communities. The pursuit to recover the tech also reveals the temptations and consequences of contact with the unknown.

  2. 02

    Transformation

    The protagonist undergoes a physical and psychological transformation after interacting with alien tech. Billy’s skin changes, his demeanor grows more grotesque, and his capacity for violence escalates. The transformation isolates him from friends and family, turning curiosity into danger. This theme examines how power can degrade innocence and erode humanity.

  3. 03

    Secrecy & Control

    Authorities move to suppress information about the incident, signaling a defensive stance against public knowledge of alien contact. The investigation becomes as much about concealing truth as addressing the threat. Secrecy reflects distrust in institutions and highlights how fear dictates decision-making in crisis situations.
