1984. Kenneth Bianchi's multiple personality defense begins to unravel, as psychologist Martin Orne and police investigators begin piecing together a disturbing real-life profile of the defendant and his codefendant, Angelo Buono. It is discovered that both men ran a prostitution ring using young women. Suspicious, Orne tricks Bianchi into creating a new personality, which proves he is lying and does not suffer from multiple personality disorder. Results of a Rorschach test are also damning. But when a search of Bianchi's home nets a cache of psychology books and a letter proving that Bianchi posed as a psychologist, he drops his insanity plea, testifies against Buono, and the two are convicted of the murders.
