There were two series of 'Back up' and they were both very good entertainment. Basically it is a series about a section of the Special Patrol Group ( SPG) They work has a crew of experienced male and female Constables working in uniform or plain clothes. They are based in Birmingham in the Digbeth area but can be called upon to assist any of the West Midlands Police areas, although they would mainly be in Birmingham. Their speciality is Public Order but they are in a position to provide back up for more or less anything. In real life, Officer on the SPG are very fit and highly trained. The officers portrayed in this programme are rather less fit. Several of the cast have gone on to bigger and better things but others have disappeared without trace.
