They're back on the streets of Newtown, helping those in need while bringing a firm hand to those who stray from the law. These six colour episodes from 1972 make up the second collection of releases, capturing characters and crimes that shaped old-school policing and made Z Cars one of TV's most popular cop series ever.

Under the watchful eyes of Detective Sergeants Stone and Haggar, with Sgt. Lynch on hand to sort the boys out, long-serving favourites, PC Skinner, Yates, Quilley and company take on crimes as varied as a witness to armed robbery threatened by gangsters; the case of the runaway dumper and the damaged Panda; a lone woman's warped revenge on a hapless burglar; a criminal inheritance on the estates that leads to new crime in Newtown; and more.

It's a hard world and a 24-hour day for the police that man these streets. But they're here so you can sit back, buckle-up and let the criminal underworld of Newtown know that Z-Cars are on the way.
