Howard Anderson, a restless and discontented American, goes to Australia to team up with an old associate, Julian Fane. They plan the construction of a holiday resort.

While Anderson is a builder who takes pride in his work, Fane's only motive in building is to burn down the resort in an insurance fraud. He hires an arsonist to carry out the work.

Unfortunately, Fane's plans are triggered too soon and result in murder. Anderson, suspicious about events, forms an alliance with George Engels, an insurance investigator.^[1]

The film was inspired by the Sydney bush fires of the 1979-80 summer. John Seale shot footage of the fire which Brian Trenchard-Smith turned into a 25-minute film, That Dangerous Summer. It was then announced this material would be used by Trenchard Smith in a feature version of the story, to be called Bushfire. In the end, Trenchard-Smith did not direct, and Quentin Masters did. Actor Ian Gilmour broke his leg during filming.^[2]

A Dangerous Summer grossed $33,000 (equivalent to $130,767 in 2022) at the box office in Australia.^[3]
