Computer security investigator Julie Blake and partner Vic Paoli are hired by NASA to track a "hacker" who is threatening an upcoming shuttle mission. There are rumblings that the infiltrator is not of this world, but when one of the astronauts is murdered, Julie knows that the culprit is very much an earthling--with an alien sense of right and wrong.
