Sgt. McKellar cautions three notorious troublemakers, Watson, O'Toole and Jones, who hire an Aboriginal worker, Wongerra, to guide them to the new gold find at Ben-Ga-Dee Creek in return for a few bottles of spirits. Jones suspects that Wongerra is taking them on a wild goose chase and tortures Wongerra, leaving him tied to a tree. He is found by Sgt. McKellar, but it is too late to save his life. Comm. Fitzalan is determined that the troublemakers will be brought to justice.
