A man is found shot dead in a hotel room and the cash he was carrying has gone missing. We discover the man owed his ex-wife thousands of pounds in unpaid child support and was lying to his girlfriend about his line of work. DS Sam Casey (Paul Nicholls) and DS Ronnie Brooks (Bradley Walsh) also learn he has a son dying of leukaemia, but hadn’t been tested for a bone marrow match.
Attention turns to the ex-father-in-law, Philip Donovan. Did he hunt down the father of his dying grandson to try to recoup the unpaid money or is there more to this family set up than first appears? How far will a parent go to protect their child…?
Meanwhile, at the CPS Jake (Dominic Rowan) and Kate (Georgia Taylor) work out their differences and reach a more even keel.
