Victims turn up cut in half and the police call in John. DNA leads to a suspect locked up in an asylum who claims he can leave the place in dreams. John tracks the man's twin brother, actually a transsexual, and after another victim turns up he concludes that the twins were separated at birth and the victims are the child-service officials who had them separated and their mother is the one taking revenge.

Meanwhile, after hypno-regression therapy fails, John tries dating which doesn't go over well. After a brief sensory-deprivation session with the asylum doctor, Jansen, John has some vague visions but Jansen disappears along with the session tape. The police believe the same killer disposed of Jansen, but we find out he's been killed by the mysterious woman we saw at the end of the previous episode.

Doe suspects a link to his own identity when a naked man with a similar brand and no recollection of who he is washes ashore from Horseshoe Island, similar to Doe's arrival in town.

John is hit by lightning on his chest-brand and can see in color — going to see a fresh body, John realizes he's also lost access to his vast supply of knowledge and all the physical talents it provided. It's not a good time as a killer strikes, leaving a kidney from his victim with the promise of more to come. The killer strikes again with two killings as John tries to come to terms with his newfound ignorance and the loss of his money when he can't call the shots for his broker. John is bitter and reluctant to admit his newfound loss to anyone, and a disappointed killer threatens to come after him. It turns out that two women, sisters, are working as the killers and lure John into a trap — fortunately John figured the killer(s) were women and he'd be targeted and the police have him wired and are watching. While pursuing one of the killers John is hit with electricity again and is back to being color-blind and super-smart.
