Detective Chief Superintendent Tatton asks PC Bradley to harbour Barry Ross, who has turned queen's evidence at the trial against crime boss Michael James Duggan. To keep Duggan from finding Ross the whole matter is to be kept secret and Bradley cannot even tell his friends and colleagues. Not even his superiors. When Ross needs medical attention Jackie sends for Dr. Tricia Summerbee, whom she knows can be trusted. Greengrass has moved to the West Indies to live with his sister, who has won a lot of money and wants to share it with him. Bernie Scripps' stepbrother Vernon arrives in Aidensfield and moves in with David at Greengrass' cottage. Vernon is quite an entrepreneur and he has lots of ideas on how to improve Bernie's business.

Dr. Merrick responds to a call from Katie Barnwell saying that her father is not feeling well, but Katie's big sister Meg insists that everything is OK and that there is no cause for alarm. But Dr. Merrick discovers that everything is far from OK when she finds the father dead in his bed and Meg trying to cope for herself and her two younger siblings in an attempt to keep the family together. Now it is up to the child welfare and they want to separate the children. Oscar Blaketon's attempt to prevent this is hampered by Robert Barnwell who is caught stealing some food. Robert is also the suspect in a number of break-ins in the village. Vernon Scripps has not been discouraged by the loss of his big fortune and a caravan site is a good a way as any to start a new one. But it takes more to make a successful caravan site than just finding a suitable field and putting up a few shacks.
