Season 1

In 1987 a teenage girl escapes from a lakeside compound. She triggers the police to raid the property and rescue her siblings - a group of bleached-blond children. Who are these children? What is this cult called The Family?

While the children rescued from the cult struggle to integrate into the outside world, detectives dig into the cult leader's past. Her followers won't talk, but detectives track her on the run between the UK and the USA.

The Family cult's solicitor testifies and reveals enough evidence for a warrant to be issued for the arrest of cult leader Anne Hamilton-Byrne and her husband Bill. Will justice be done for the children she imprisoned?
