The Return of the Prodigal Son is the 184th episode of The Bill.
Greig has been made Acting DI, so an unimpressed Roach takes it up with Conway when he gets back. Roach is bringing in a prisoner who has been on the run for 12 months and showed up in Belgium. His solicitor wants bail because he is terminally ill. His mother and sister are coming in later to see him, and the prisoner wants them to take his suitcases home.
An officer from the Drugs Squad turns up looking for D.I. Burnside. Heroin is going to be delivered on the estate and they want Sun Hill CID to assist with an operation to recover it. The sniffer dogs go berserk when they go past the suspect's cases.
Suzanne and Reg are out looking for a drunk, but arrest another one. When they put him the van they notice a group of men who take off when they see the officers. Before they can give chase, they hear an explosion. Ford goes into the caretaker's burning flat to rescue his daughter. The caretaker has been discovered to have been dealing drugs.
