Mistress Electra who also goes by the name the Big Boss, is a white-skinned and red-haired villainess. She wears a little light blue outfit with gold lightning bolts coming out from her top. She has a capital "E" buckle on her belt.
She is in charge of four minions, known as Carra (Lita Vasquez), Orak (Eva Linda), Noche , and Mahiya . We know that Noche and Mahiya were played by Liza Zobel and Diana Villa, but we are not sure which is which.
The plan of the Planet Women is to kidnap a bunch of Earth's leading scientists, force them to design, build and embed huge engines into the center of the Earth. Then they plan to fly the whole planet back to the Planet Women's home system. In so doing this, they would be stopping the planet's rotation and breaking its orbit, which will kill all the inhabitants.
It is up to Darna (Vilma Santos) to thwart her plan and defeat the Planet Women.
The Planet Women hypnotize Ramon (Zandro Zamora), Darna's boyfriend, and use him to lure Darna into a trap. At the village a massive storm takes place, and Mistress Electra plays damsel-in-distress, hoping Ramon will come out to save her. He does, carrying her inside and quickly stripping Electra to the waist to get her out of her wet clothes.
Electra then uses Ramon as hostage to get Darna to gather up the scientists. Darna challeges Electra to a winner take all fight. If Electra wins, Darna will help the Planet Women enslave the Earth. If Darna wins, they have to pack up all their evil plans and head home. After a few minutes of a splendid catfight that includes in air fighting, Darna gets Electra into a submission hold which ends the battle. Electra then honors her word and flies off in her ship never to be seen again.
Darna became a cultural icon in the Philippines, created in 1947 when the country was struggling to come out of the devestation of World War II. She became one of the first heroines in film in 1951, and she inspired 14 movies along with countless shows, magazines, spoofs and spin-offs. She served as a salve to a country looking for a champion, and became ain icon of Truth, Justice and the Filipino way.
