Members of an elite squadron of mutants, the telepathic twins, Ellie and Mika have specialized skills that will enable them to steal the top-secret formula for an age-reversing drug developed by rebel scientists on the wild side of The Wall. Juiced by these potent pills, the cadaver-like Gorman foresees a future in which he'll be forever young - released from the machinery that now supports him. Unless the twins have a master plan of their own: to bring the all-powerful Gorman to his knees, and face-to-face with his greatest fear.
