Project Questor is brainchild of the genius Dr. Vaslovik: he developed plans to build an android super-human. Although he's disappeared and half of his programming tape was erased in the attempt to decode it, his former colleagues continue the project and finally succeed. But Vaslovik seems to have installed a secret program in Questor's brain: He flees and starts to search for Vaslovik. Since half of his knowledge is missing, he needs the help of Jerry Robinson, who's now under suspect of having stolen the android.
