Renowned scientist Dr. Joe Messenger lives in Salt Lake City with his beautiful wife Karen and his son Jack. His research in the study of human immortality centers on a human-like super-computer that controls many of Salt Lake City's daily operations and has access to vast amounts of information. When Juliet Spring joins Joe's research team, they embark on a series of experiments to prove that the human mind can exist within a computer. Juliet seduces Joe and reveals that she is dying from an inoperable brain aneurysm. She insists on being his first human experiment. She is convinced that immortality is possible by downloading her mind into the computer. Joe refuses Juliet's request and tries to break off all contact with her but she is determined to get what she wants.
