Narrative tropes
One Hero Changes Everything
highArgo City faces extinction and Earth faces magical conquest — crises demanding collective response — yet no governments, institutions, or Argo City's own people act. Kara alone pursues the Omegahedron, alone survives the Phantom Zone, and alone defeats Selena. Without her, Argo City dies and Earth falls. Collective action is wholly absent; the hero's individual powers and will are the sole decisive factor.
About this trope: One exceptional individual matters more than institutions or collective action. Problems affecting millions are solved by a single remarkable person. Everyone else is passive.
Violence Gets Results
highNo negotiation with Selena is ever attempted; the climax is an outright superpowered battle in which Supergirl uses a focused whirlwind to physically trap and destroy her. Kara's primary problem-solving tool throughout is her Kryptonian combat ability. Victory is achieved by physically overpowering the antagonist and sealing her away, and the film never raises any question about whether this was the right approach.
About this trope: The central conflict is ultimately resolved through physical force rather than negotiation, diplomacy, or systemic change. Talking fails; fighting works.
Born Special
mediumKara's powers derive entirely from Kryptonian birth — the yellow sun activates abilities no human could acquire through any training. Her ancestry (Kryptonian lineage, cousin of Superman/Clark Kent) is foregrounded as the source of her capability. No other character can challenge Selena's demons or rescue Ethan; Kara's specialness is purely innate, not earned through effort or choice.
About this trope: Certain characters are inherently special by birth, blood, genetics, or prophecy — not through effort or choice. Greatness is innate, not earned.
Cultural messages
Power Means Duty
mediumKara's extraordinary powers immediately create an obligation: she must retrieve the Omegahedron or Argo City perishes. At the story's end she sacrifices her budding romance with Ethan to fulfill that duty and return home — personal happiness subordinated to the greater good. Zaltar's voluntary self-exile as punishment for losing the artifact reinforces that power and custodianship carry inescapable moral weight.
About this message: Those gifted with extraordinary abilities, wealth, or status have a moral obligation to use them for others — and the weight of that duty can be crushing. Privilege creates obligation.

Full plot (spoilers)
In Argo City, a surviving Kryptonian community existing in a pocket of trans-dimensional space, young Kara Zor-El (Helen Slater) is shown the Omegahedron by the eccentric artist and city elder Zaltar (Peter O'Toole). The Omegahedron is an enormously powerful artifact that also serves as Argo City's primary power source; Zaltar has borrowed it without the city government's knowledge. During Kara's visit, an accident sends the Omegahedron hurtling through a portal into space. Without it, Argo City will die. Kara immediately follows it through the portal and arrives on Earth, where the planet's yellow sun grants her Kryptonian superpowers.
The Omegahedron lands near Selena (Faye Dunaway), a power-hungry carnival fortune teller and amateur witch. She quickly realizes the artifact amplifies her magical abilities and begins using it to make herself a self-proclaimed 'princess of Earth,' conjuring monsters and commanding increasing influence alongside her mentor Nigel (Peter Cook) and her dim-witted companion Bianca (Brenda Vaccaro).
Kara assumes the human identity of Linda Lee, presents herself as a cousin of Clark Kent, and enrolls at an all-girls boarding school where she befriends Lucy Lane (Maureen Tully). She takes a job investigating the school's grounds and comes into contact with Ethan (Hart Bochner), a handsome groundskeeper. Selena also becomes infatuated with Ethan and uses a love potion derived from the Omegahedron to enslave him as her consort. Kara, in her Supergirl guise, rescues Ethan from Selena's enchantment; free of the potion's effect, Ethan genuinely falls for Kara/Linda instead, enraging Selena.
Selena escalates her attacks, and eventually uses the Omegahedron's full power to banish Supergirl to the Phantom Zone, a bleak extradimensional void where Kara loses her Kryptonian powers. Stripped of her abilities, she wanders the desolate landscape and nearly drowns in an oily bog. She eventually discovers Zaltar, who entered the Phantom Zone voluntarily as self-imposed punishment for losing the Omegahedron. Although weakened and near death, Zaltar uses the last of his life force to breach the boundary of the Phantom Zone, sacrificing himself so Kara can escape.
Back on Earth, Kara regains her powers under the yellow sun and confronts Selena for a final battle. Selena summons a massive shadow demon to destroy Supergirl, but on Nigel's inadvertent advice Supergirl generates a focused whirlwind that traps Selena and allows the demon to turn on her. Selena and her allies are dragged through a mirror portal and sealed away. Ethan confesses his love for Kara but understands she must leave to save Argo City. In the final scene, Kara returns to a darkened, dying Argo City and restores the Omegahedron, causing the city to light up once more.
