The show was originally scheduled to appear in 2004, entitled "Rapid Response". The pilot was shot, based on an episode of "Police Rescue" and starring Matthew Le Nevez, Paul Pantano, Libby Tanner and comedienne Corrine Grant in a dramatic part. It was not until the US writer's strike put a halt to Ten's US content that the show was resurrected (along with a revamped Good News Week), with a new cast (two of whom had just experienced success in another Melbourne-based crime drama on Channel Nine, "Underbelly"), edgier style and original script.
