TV3 are quick off the mark with the ould documentaries of late, so it's no surprise that they're bringing us this tale of the kidnapping of Amanda Bert, Georgina DeJesus and Michelle Knight. These three girls were held captive in a cellar in Cleveland, Ohio for between 9 and 11 years, while their families maintained hope that they would be found alive. This documentary explores what happened to the girls during their imprisonment, and tries to figure out what could have motivated their captor, Ariel Castro, to carry out such a horrendous crime.
