He opens the attachment and finds out that the code is a set of instructions on how to generate a fake identity. He realizes that someone is trying to frame him for a crime. He does not know who sent the email or why they sent it to him, so he tries to figure things out on his own.

Meanwhile, the Machine alerts Harold and John about Henry Peck's impending danger. They begin to investigate and discover that Henry Peck has written a code that can break into classified government databases. The government suspects that he is planning to use the code to steal top-secret information. However, they do not have any evidence to prove their suspicions, so they decide to set a trap for him.

Harold and John realize that the code Henry Peck wrote is not harmful or intended for any ill purposes, but it can be used for illegal activities. They begin to investigate further to uncover the truth about who is framing him. They discover that one of Henry's co-workers, Alicia Corwin, had asked him to write the code for her and that she was involved in the plot to frame him.
