Detective Inspector Henry Crabbe (Richard Griffiths) plans to retire after 25 years on the Force and opens his own restaurant – Pie in the Sky – much to the dismay of his superiors.
After being shot on duty in his last case, his decision is reaffirmed; however when his conduct on that case is called into question he is forced to continue on a part-time basis by the duplicitous Assistant Chief Constable Freddy Fisher (Malcolm Sinclair), who is fully aware that Henry is the main reason why so many crimes get solved.
