(First broadcast on July 6, 2009 replacing ID Elite at 9:30 PM) This series was filmed with the sponsorship of the Hong Kong Fire Services Department. It is a key promotional drama for TVB in 2009, produced by Wong Sam-wai. This series is part of the TVB 2008 and 2009 Program Preview, serving as a continuation of the series "Within the Fire" and "Within the Fire II". However, it has no connection to the previous two series in terms of storyline. Some fire and explosion scenes were filmed in late June 2008 within the premises of the pre-demolition Wong Chuk Hang Estate arranged by the Housing Authority, while other parts were filmed in an industrial building near Tai Kok Tsui close to the Kai Tak Tunnel.
