The first two series, entitled Rockliffe's Babies, starred Ian Hogg as Alan Rockliffe, a detective sergeant assigned to train a team of inexperienced plain-clothed Crime Squad PCs in inner-city London, which include Steve Hood (Brett Fancy), Gerry O'Dowd (Joe McGann), David Adams (Bill Champion), Janice Hargreaves (Alphonsia Emmanuel), Paul Georgiou (Martyn Ellis), Keith Chitty (John Blakely) and Karen Walsh (Susanna Shelling).

[1] The series featured writing contributions from Richard O`Keeffe, Don Webb, Charlie Humphreys and Nick Perry, and was directed by Derek Lister, Keith Washington, Clive Fleury and David Attwood.

The seven episode third series proved to be the last, with many citing a change in the programme's formula for the heavy decline in viewing figures.

[3] Most of the location filming featured in the first two series took place around the Kensal Rise area of West London.

[4] After many years of remaining unreleased, the complete series was released on DVD by Network distributing on 8 May 2017.
