What happens in Supergirl (1984)? — Full Plot
We open on Argo City — a remote Kryptonian survivor colony hidden in a pocket dimension, where Krypton's remaining citizens survived the planet's destruction. Kara Zor-El (Helen Slater) lives there as a 16-year-old, raised by her parents Zor-El and Allura. Her mentor Zaltar (Peter O'Toole) accidentally drops a power source called the Omegahedron into the void.
The Omegahedron is Argo City's central energy source. Without it, the city will lose its protective bubble within days. Kara, having recognized her abilities as similar to Superman's, volunteers to retrieve it. She follows the Omegahedron through interdimensional travel and arrives on Earth.
On Earth, the Omegahedron has fallen into the hands of Selena (Faye Dunaway) — a witch who has been practicing failed black magic for years. She immediately recognizes the artifact's power and intends to use it to dominate humanity.
Kara, now Supergirl on Earth, attends a Mid-American boarding school under the false identity 'Linda Lee.' She befriends Lucy Lane — Lois Lane's younger sister. The middle act features fish-out-of-water comedy as Supergirl learns about modern Earth — particularly American teenage culture and the existence of Superman as her cousin.
Selena uses the Omegahedron to summon demonic creatures, including the Phantom of the Shadow — a black-and-grey demonic entity that nearly kills Supergirl. Kara escapes by using her flight powers and her Kryptonian biology against the Phantom.
The final battle is at Selena's gothic mansion. Supergirl, Lucy Lane, and a redeemed Zaltar (who has been searching for Kara across dimensions) confront Selena. Selena is defeated when Supergirl traps her in a magic mirror. The Omegahedron is recovered. Kara returns to Argo City to restore the power source.
Supergirl grossed $14 million globally on a $35 million budget — a devastating commercial failure. The film's negative reception derailed both Helen Slater's career and any planned Supergirl sequels. The character would not appear in another live-action film until The Flash (2023) and her own solo film Supergirl (2026).
