Billy Milligan was arrested in 1977 for a series of robberies, kidnappings, and rapes of three women on the
Ohio State University campus. Despite evidence suggesting he had committed the crimes, Milligan had no memories of the assaults, appearing to exhibit continually changing personality traits. This resulted in a team of psychiatrists diagnosing him as having
dissociative identity disorder. His lawyers pleaded
insanity, claiming two of his initial 10 personalities committed the crimes without Milligan's knowledge. Milligan was acquitted but spent the next decade in mental hospitals, where he was diagnosed with an additional 14 personalities. He was released in 1988, then discharged from the Ohio mental health system and Ohio courts in 1991. His life outside the system of trying to lead a normal life is also discussed. == Cast ==
