Recovering alcoholic Jim Bergerac, a sergeant in the Jersey police force, returns to the island after a period of absence during which he has recovered from injuries sustained on the job. Nonetheless he is not considered fit enough to join the newly-formed Bureau Des Etrangers, headed by Inspector Crozier. Thus Jim does some unofficial sleuthing into the death of colleague Tom Draycott, and, helped by Draycott's girlfriend, artist Francine, uncovers a plot to sell arms to South Africa. His success in catching the culprit leads to his being accepted into the bureau though he still has to contend with the reluctance of his ex-wife Deborah, daughter of shady millionaire Charlie Hungerford, to see their daughter Kim.
