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.

Many viewers stated that the success of the two Babies series came not from Rockliffe himself, but from the popular ensemble cast.
