The series recounts the career and sexual offences of Jimmy Savile, who was one of the best-known radio and television personalities in Britain during his life, and whose crimes emerged after his death. Four real-life survivors of Savile's abuse speak at the start and end of some of the episodes. Each episode has scenes taking place in the last years of Savile's life, primarily where writer Dan Davies, who is researching Savile for his book, interviews him in various locations.
