Detective Sergeant Nicky Cole (Don Gilet) blows the whistle on a senior police officer guilty of corruption in London. Cole is then shunted up North to avoid any difficulties or fallout, and ends up in Newcastle upon Tyne as a Detective Sergeant in a busy CID with the fictional Tyneside Police. To begin with, he finds himself on the night shift and becomes increasingly frustrated at the inspector - DI Carter (Christian Rodska)'s - desire to keep him there despite the fact that his ability and motivation clearly exceed the demands of the job.
