Beth Winters, a Canadian reporter, has come to the small Australian Outback town of Gamulla to shoot a story about the local dog food packing plant, which uses the meat of poached kangaroos in its product. When Beth disappears one night, her husband Carl arrives to find out what happened. Beth apparently ran afoul of the psychotic Baker brothers, who work in the plant. But crusty old Jake Cullen soon learns that Beth was a victim of a giant razorback, the same one that carried off his grandson years before and which he has been hunting ever since.
The Australian Outback becomes an almost alien world - desolate, strange and scary where any form of undiscovered life might exist. You don't get to see much of the giant pig, admittedly, but then they didn't have CGI back in the early 80's. The real menace of this movie lies with the kangaroo poachers, two brothers who reek of malevolence and filth all the way through the film. They were truly terrifying, and the insane laughter of David Argue (playing younger and more dangerous brother Dicko) still haunts me to this day.
