Marcia Reynolds, an average Earth girl living in the 21st century, is kidnapped by the Brain Lords of the planet Cymradia, who determine that she has the potential to be a strong and courageous leader. They rename her "Futura" and plan to use her in a scheme to transfer their minds into the bodies of powerful humans. Unfortunately for them, their assumptions about Futura's potential as a leader are proven right when she escapes and leads a rebellion against them.

After Futura escapes, the Brain Lords turn their attention to some of their other human victims, choosing one to be their test subject for "Project Survival."
