Complete story — includes the ending

Continuing on from the last episode where it was shown that he was the last person to apparently have seen Finn Tyler alive, DS Sam Casey is suspended from duty pending a full investigation. Convinced of Sam's innocence Ronnie does some sleuthing of his own, with DI Wes Leyton getting hands on with the investigation. Discovering that CCTV footage of Tyler in his cell has gone missing, this in turn leads him to discover a pact made by the bereaved relatives of the train victims and to the real killer. Meanwhile, For the first time we explore a day-in-the-life of the Law & Order: UK regulars. Jake and Kate argue over the morality of prosecuting a mentally ill man like Tyler and indeed over most things but declare a truce over a broken coffee machine and after a few drinks Jake opens up to new colleague about his mother's death. Whilst Ronnie catches up with estranged daughter Emma ( Alexandra Guelff ). And during his suspension Sam spends the day with his son Ben (Joe Reynolds), to his ex-wife's ( Ebony Gilbert ) disapproval. All giving new insight into our heroes' off-duty lives.
