In a powerful and heartbreaking documentary, Deborah Davies profiles six men, all childhood victims of a predatory British football coach who spent his days training children and his nights abusing them.

Barry Bennell was one of the top football coaches in Britain with ties to major clubs like Manchester City and Crewe Alexandra.

Davies first reported on Bennell’s crimes two decades earlier. She has befriended his victims and has a rare insight into their plight.

According to new evidence uncovered during the investigation, one likely victim is his most famous protégé, former Wales international and manager Gary Speed, who took his life in 2012.

The investigation shows that high-profile clubs, as well as England’s Football Association, failed to protect children and in some cases failed to act on warnings.
