Dr. Emilio Lizardo, incarcerated at the Trenton Home for the Criminally Insane, sees a television news story of Banzai's successful test. In 1938, Drs. Lizardo and Hikita had built a prototype overthruster, but he tested it before it was ready and became stuck between dimensions. He was attacked by aliens until freed by his colleagues, emerging changed and violent. Understanding that Banzai has finally accessed the 8th dimension, Lizardo escapes the asylum and plots to steal the overthruster.
