With the help of her father's greatest creation, a holographic computer named Synergy, Jerrica Benton and her sisters team up to create the band Jem and the Holograms, who will go head-to-head with their rivals, the Misfits and their greedy road manager Eric Raymond, in a battle of the bands for control of Mr. Benton's music company, Starlight Music.

Using a holographic computer she inherited from her father, Jerrica Benton turns herself and her pals into pop-music group Jem and the Holograms.
