Supergirl

A small fraction of the long lost planet Krypton, now named Argo City, remains in the cosmos. A magical place, powered by the mysterious 'Omegahedron'. Among the residents is a young Kara Zor-El, played by Helen Slater.

She is the cousin of Kal-El whom we all know on Earth as Clark Kent, better known famously as Superman!

Kara's world is thrown into sudden jeapordy when she is almost blamed for the vital power source of the inner-space Kryptonian city (The Omegahedron) blasting off into the great unknown.

Knowing that she is the only person to retrieve it, Kara's curiousity gets the best of her and she sets off after the power source and ends up on planet Earth where her cousin also lives.

Now decked out in a female version of the Superman costume, Kara soon becomes known as... Supergirl.

Unfortunately her search for the Omegahedron is endangered as it has fallen into the hands of Selina (Faye Dunaway), an evil witch who plans to use black magic along with the power of the Omegahedron to bring the world to its' knees before her.

Its a race against time for Kara to find the power source and return it to her homeworld before all is lost!
