Set and filmed in Liverpool, this fictional drama follows the Mitchell family as they struggle to cope with the devastating aftermath of abuse committed by one of their own.

The official synopsis reads: "Having served his prison sentence, Joe (Bobby Schofield) arrives at St Maura's, an institution which offers him a home and rehabilitation after his release. With the support of Katherine (Anna Maxwell Martin), an ex-nun, Joe undertakes therapy sessionsin the hope of understanding what led him to commit the abuse.

"Simultaneously, his sister, Anna (Anna Friel), is dealing with the enormous impact that Joe's crime has had on her family - her sons, Tom (Austin Haynes) and Peter (Fin McParland), and her father, Brian (David Threlfall). The drama examines the extensive ripple effect of abuse from multiple perspectives and how those involved can try to move forwards in the midst of the devastation."

Speaking of the inspiration behind the drama, McGovern revealed: "I received a letter from a woman who works with sex offenders and wanted to speak to me. She spoke no holds barred about her job and working with sex abusers. She told me certain facts and figures that are quite unbelievable, so I want people to watch the film and learn things about child abuse. I felt compelled to write about it."
