When therapist-in-training James O'Neill starts his placement at a therapy centre in West London, his first referral is Abraham, a silent and frightened young man in a tightly zipped, hooded anorak. After spending the majority of their initial sessions in silence, O'Neill gradually gains Abraham's trust and learns of the abuse and violence he was subjected to as a child that caused him to hide away from the world - barely sleeping, too frightened to get undressed and shower, anything to make him that vulnerable. Over the many years they meet, Abraham's unfolding story and bravery inspires O'Neill to confront his own complicated past.
