A pair of con men sneak into Five-O' headquarters at night to photograph the layout of the offices. They then use these photos to duplicate the offices in an abandoned building, and also hire actors to impersonate McGarrett and the other members of Five-O, as part of an elaborate scheme to extort money from businessmen who may not be aware of the real location of Five-O, nor personally acquainted with its top operatives.
