The second of three drama-documentaries telling the stories behind cases featured on Crimewatch UK. For years, Olympic swimming coach Paul Hickson had sexually abused the teenage girls in his care. An alert off-duty policeman and one girl's courage in speaking out prompted a two-year criminal investigation that led to Hickson's imprisonment. Narrated by Jill Dando. The final programme will be shown later this year. See today's choices.
