During a mission Darien gets a back injury, and the Official refuses to pay for treatment. Seeking out an accupuncturist, Darien inadverently reveals he can become invisible. On his next visit, the accupuncturist, Charlene, inserts needles that allow her to use electricity to put Fawkes in agony if he doesn't obey her. She needs a rare set of mystical needles to cure her mentor, and Darien to steal them. He succeeds, but the needles have "bad chi" because the original owner, a millionnaire, stole them. The millionnaire has to be killed to eliminate the bad chi, but Charlie can't do it without gaining bad chi. So she forces Darien to try. Needing Counteragent, Fawkes manages to leave a clue so that the Agency can follow them, and prevent the murder.
