Tina Dakin (Anna Maxwell Martin) stands silence and tense in the dock. She has told the truth and now all she can do is await to hear the verdict.
It is some months earlier and Tina, a happily married mother of three young children, is overstretched at home and at work. She and her husband struggle to make ends meet.

On an ominously cold day Tina accompanies a new inmate, Stephen Cartwright (Robert Sheehan), into the young offender’s institution where she works as a prison officer. As she runs through the ground rules with Stephen and shows him into his cell she senses that something isn't right.

She notifies her senior officer Frank (Ewen Bremner) of her concerns. But an emergency elsewhere demands her attention and when she returns her worst fears have become a very real tragedy. It appears that Stephen has taken his life. Her gallant attempts to resuscitate him fail, and before long she will come to face to face with his father, Peter (John Bishop), in the worst circumstances imaginable.

But Tina’s troubles have only just begun and a series of betrayals and cover-ups result in her becoming the victim of a terrible crime.

Now Tina is on trial for taking the law into her own hands. What will her fate be?
