The case of the Austrian man who kept his daughter prisoner for 24 years in the cellar of his house, until she was released in 2008 at the age of 42. Dramatically pleading guilty to all of the charges at the last moment of the trial, he was sentenced to life in a secure unit for incest, imprisonment, raping the victim - who bore seven children - and causing the death of one child by neglect. This documentary explores the crime itself, Fritzl's trial and the aftermath for everyone involved, and ponders how anyone can possibly recover from such an ordeal.
