S01E01 Into Etheria
Sorceress discovers a gateway to another world. She sends Prince Adam and Cringer in to investigate. They find the new world to be enslaved by Hordak and his second in command, Adora.
Adora is captured and taken to Beast Island. She escapes from prison, but hurts her head and loses her memory. She then encounters a primitive human tribe of Beast Warriors and has to face the Great Beast.
She-Ra, He-Man's twin sister, is leading a group of freedom fighters known as the Great Rebellion in the hope of freeing their homeworld of Etheria from the tyrannical rule of Hordak and the Evil Horde.
