The Central Intelligence Agency is secretly developing "Crossbow", a space shuttle-mounted laser weapon precise enough to incinerate a single target from outer space, planning to use it for illegal political assassinations. However, they struggle with its power source, and have covertly hired Professor Jerry Hathaway at Pacific Technical University to develop this. Hathaway has assembled a group of genius students in physics to do the work for him, though outside of his graduate student Kent, purposely does not tell them the reason for their research.
