The show centers on Jem who is an upcoming rock star with her band The Holograms. Jem is also the alias of Jerrica Benton, the daughter of a music executive who after his death, should rightfully be in charge of the company Starlight music. Jem/Jerrica's rival is the sneaky and evil Eric Raymond who is trying to control stalight music and get Jerrica out of the picture. Eric creates a band called the Misfits who are supposedly rebellious rockers. With the help of a secret computer/hologram machine named synergy created by Jerrica's father, Jerrica and her sister Kimber and their friends create Jem and the holograms to compete in popularity at the same music label. Of course, no one but the girls are in on all of this. Also in play is a never-resolved love story of Jerrica and her boyfriend Rio who just happens to be with Jem at the same time, but has no idea its the same girl. Jerrica has the ability to transform to Jem and back again through her magic earrings. Throughout the show the girls encounter many a sabotage plan, heartbreak and of course impossible dangers followed by even more impossible rescues. But it still remains one of the best 80's cartoons ever!
