Monsters Inside: The 24 Faces of Billy Milligan (Season 1)

Monsters Inside: The 24 Faces of Billy Milligan (2021) is a true-crime docuseries you can watch online on iFILM. In late-1970s Ohio a man accused of a string of rapes goes on trial, and his defense floats an argument the country had never taken seriously in court: the crimes were committed not by him, but by other people living inside his mind.

Billy Milligan claims more than two dozen distinct personalities share his body, from a frightened child to a cold-blooded Yugoslav, each taking control in turn. The court is left to weigh something genuinely new: can you convict a man for what was, in effect, not his own hand? The series untangles the case through archival tapes and the voices of doctors, lawyers and people who knew Billy, keeping one question honestly open. Brilliant act, or a mind truly split apart?

Directed by Olivier Megaton, the four episodes are arranged so that whichever version you believe early on starts to crack by the end. It lands best for true-crime fans, especially anyone drawn to stories caught between psychiatry and the law. Stream every episode of Monsters Inside: The 24 Faces of Billy Milligan online on iFILM.
