The 1985 film Red Sonja is a sword-and-sorcery fantasy film set in the Conan universe. It stars Brigitte Nielsen as the title character Sonja, along with Arnold Schwarzenegger as Lord Kalidor.
The movie has a musical score by Ennio Morricone.
Queen Gedren (played by Sandahl Bergman) murdered Sonja’s family after she rejected the queen’s advances. After Sonja (played by Brigitte Nielsen) calls out for help, a red goddess appears and grants her fighting skills and strength, but these powers will only stay with her if she is never with a man unless he defeats her in battle.
Varna, Sonja’s surviving sister, is a priestess who wants to banish a mythical relic named the Talisman which created the world. Only women can use this Talisman, but it has become too unwieldy. As the priestesses prepare to banish the Talisman, Queen Gedren and her army attack the temple and slaughter them. Varna escapes and is found by Lord Kalidor (played by Arnold Schwarzenegger) but she dies as soon as he brings Sonja to her. Varna tells her in her dying breath to destroy the Talisman.
Heading towards Gedren’s realm, Sonja fights through various trials. Gedren’s warlock sees her approaching in a magic mirror, and sends a beast to attack her. Kalidor saves her from the beast, and Sonja accepts his help as he reveals he is part of the ancient family that helped originally position the Talisman in the temple. He fights her and attempts to defeat her in order to have her, but the battle is a draw.
They arrive at Gedren’s castle, and the queen retreats to the Chamber of Lights. The Talisman cracks the floor, and a pit of lava opens up. Sonja kills the queen and throws her into the lava. Sonja also destroys the Talisman by throwing it into the molten lava, and the castle is destroyed in the resulting explosion.
