Terry Dyer has been recently released from prison, where he was imprisoned for a crime he still maintains he did not commit, and he returns to his East London estate in search of the truth. The father of the victim he was convicted of killing, Ken Randle, confronts and wounds him. D.C.S. Walker is empathetic to Ken's situation and releases him on bail, and then Ken soon becomes doubtful of Dyer's guilt, growing convinced that a friend of his son's was involved in his murder, and soon long-buried secrets are unearthed, leading to an unexpected twist, while D.S. Satchell finds his career may be in danger.
