Heatwave is the mildly interesting story of a woman's attempt to stop a redevelopment plot which she thought was the cover-up for fraud and other criminal activity. Kate (Judy Davis), through her own efforts, manages to find some evidence to support her claims and also have a romance. Davis gives an energetic performance as the crusading woman, but the script lacks a convincing plot or characters. While it has some good moments, Heatwave is primarily notable because it was one of the earlier efforts of Australian director Phillip Noyce, who went on to make the very exciting Dead Calm.
