What Happens in Heavy Metal: Full Plot Summary

The whole story of Heavy Metal (1981) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

This film is composed of various animated vignettes that delve into science fiction themes, all intertwined by the presence of a glowing green orb that embodies "the sum of all evils." This orb is first seen drifting through space prior to the film's title introduction.

Soft Landing / Grimaldi

In the vastness of deep space, a space shuttle opens its doors, releasing a 1959 Corvette that plunges toward Earth. After landing in a crop field, the driver, Grimaldi, races to a remote mansion. Upon his arrival, he is greeted by his daughter, who witnesses him open a container containing a glowing green orb. Suddenly, Grimaldi's body melts, and the orb advances toward the frightened girl, revealing itself as “the sum of all evils” in the universe and announcing that she holds untapped powers. The orb then proceeds to share tales of its existence and influence.

Harry Canyon

In a barren desert excavation site, a scientist discovers a glowing green sphere. As one alien touches it, he immediately disintegrates. This segment shifts to a dystopian New York City in 2031, where a cab driver named Harry Canyon](/actor/john-candy) picks up a punk passenger. Tensions escalate when the punk brandishes a gun and threatens Harry, who swiftly activates a secret weapon in his cab, disintegrating the thug. As the chaos unfolds, Harry encounters a stunning woman with red hair fleeing from a man named Rudnick and his thugs. He chooses to help her, taking her to the police station, but shortly after, she confesses that she is pursued for knowledge about the Loc-Nar. Their connection intensifies, leading to a night together, but the next day brings trouble as Rudnick’s goons threaten Harry for the woman's whereabouts. As the plot thickens, Harry becomes embroiled in a web of danger, deception, and survival, highlighted by a dangerous deal with Rudnick which turns unexpectedly deadly.

Den

Present-day teenager Den finds the Loc-Nar, mistaking it for a meteor, in his backyard. While experimenting with lightning, he accidentally harnesses its power, launching him across space to a strange planet where he transforms into a larger, muscular version of himself. He becomes embroiled in a human sacrifice led by a nude priestess and ultimately rescues Katherine, a technique that leads to high-stakes intrigue involving the priestess and rival factions vying for control of the orb.

Captain Sternn

The narrative shifts to a large space station near Jupiter where Captain Lincoln Sternn, charged with an array of crimes, undergoes a trial. Pleading not guilty, he employs a character witness who inadvertently reveals more of Sternn's malevolent history. The tension escalates as chaos erupts in the courtroom, and Sternn's hasty decisions lead to deadly consequences.

B-17

In the midst of World War II, a B-17 bomber crew faces treacherous situations where their aircraft is taunted by the Loc-Nar. After multiple crew fatalities and supernatural occurrences, the co-pilot’s harrowing experiences culminate in survival against grotesque transformations caused by the orb, leading to a haunting conclusion.

So Beautiful and So Dangerous

Back on Earth, the Pentagon faces bizarre incidents provoking a scientist's attention, while an unexpected abduction intertwines human fate with alien encounters. Amid comedic and chaotic happenings, interactions between androids and Earth women lead to unintended agreements and relationships aboard a colossal spaceship.

Taarna

The Loc-Nar seeks a powerful warrior, Taarna, who rises from her sanctuary to challenge the barbarian leader and protect her people. Her journey is fraught with sacrifice, culminating in a confrontation that determines the fate of her world against the malevolent will of the Loc-Nar.

Grimaldi (Coda)

The culmination of Taarna's sacrifice resonates through dimensions, awakening Grimaldi's daughter, who escapes just as the mansion implodes. In a twist of fate, she encounters Taarna’s mount, destined to become the next guardian against the reemergence of malevolence shaped by the Loc-Nar, hinting at a continuation of this eternal battle.

Heavy Metal Plot Explained: Your Questions Answered

The questions people ask most about Heavy Metal (1981): what happens in the confusing scenes, why the characters do what they do, the twists, hidden details and what the ending means. Each answer contains spoilers.

Q1

What is the Loc-Nar orb and why is it called the sum of all evils?

The Loc-Nar is a glowing green orb that serves as the central connecting element across all the film's vignettes. In the opening segment, it explicitly states it is 'the sum of all evils' in the universe. The orb appears in various storylines, tempting and corrupting those who encounter it, from a WWII bomber crew to a futuristic cab driver. Its power seems to amplify the worst aspects of anyone it touches.

Foreshadowing: The film opens with the orb drifting through space before the title, establishing its cosmic significance.

  • loc-nar
  • orb
  • evil
  • sum of all evils
  • green orb
Q2

What powers does Grimaldi's daughter possess?

After Grimaldi melts upon opening the container, the Loc-Nar approaches his daughter and reveals she holds 'untapped powers.' The orb chooses her as a target for its influence, suggesting she possesses latent abilities that the orb either wants to corrupt or exploit. This sets up the coda where her awakening leads her to become a potential guardian against the orb's evil.

Foreshadowing: The orb's direct statement about her powers foreshadows her role in the final scenes.

Q3

Why does Grimaldi melt after opening the container?

The Loc-Nar appears to kill Grimaldi as soon as he opens its container, causing his body to disintegrate or melt. This demonstrates the orb's lethal nature and its ability to destroy those who prematurely expose it. Grimaldi was likely meant to deliver the orb to someone else, but the orb chooses a new host upon reaching the mansion.

Foreshadowing: The opening space scene shows the orb drifting toward Earth, suggesting it had a specific destination.

  • grimaldi
  • melt
  • death

Q4

How are all the different stories in Heavy Metal connected?

All vignettes are thematically and mechanically linked by the Loc-Nar orb, which appears in each segment. The anthology structure shows how this single cosmic evil manifests across different time periods and settings, from ancient civilizations to the far future. The orb corrupts, transforms, or destroys anyone who possesses it, demonstrating its pervasive influence throughout human history and beyond.

Foreshadowing: The opening scene establishes the orb traveling through space before the stories diverge.

  • connection
  • anthology
  • loc-nar

Q5

What happens to Taarna at the end and what is her sacrifice?

Taarna, the warrior chosen by the Loc-Nar to dominate her world, instead fights against the barbarian leader who was corrupted by the orb. She sacrifices herself in battle against overwhelming odds, and her death resonates through dimensions, causing the mansion to collapse. Her sacrifice temporarily contains the evil but at great personal cost, reflecting the film's bittersweet tone.

Foreshadowing: Taarna was selected by the Loc-Nar but rejects its corruption, choosing to protect her people.

  • taarna

  • death
  • barbarian leader
  • warrior
Q6

The film ends suggesting she will become the next guardian against the reemerging evil, inheriting Taarna's role in the eternal battle against the Loc-Nar's malevolence.

How does Den get transported to the alien world and why does he transform?

Den discovers the Loc-Nar in his backyard, mistaking it for a meteor. While experimenting with lightning for his science project, he accidentally harnesses the orb's power, which transports him across space to an alien planet. Upon arrival, he transforms into a larger, muscular version of himself. This physical transformation appears to be the orb's influence, enhancing him physically but also drawing him into the planet's conflict involving human sacrifice.

Foreshadowing: The Loc-Nar is established as a cosmic object with immense, reality-altering power.

She confesses to Harry that she is pursued 'for knowledge about the Loc-Nar,' suggesting the orb's existence and location are secrets worth killing for in this future timeframe.

Foreshadowing: The earlier desert excavation scene establishes the orb's destructive nature when touched.

The orb causes supernatural occurrences aboard the bomber, leading to crew fatalities and grotesque transformations. The co-pilot survives but witnesses horrifying changes in his crewmates, suggesting the Loc-Nar's influence can corrupt and mutate organic matter, especially when in close proximity over time.
