Jake Cullen (Bill Kerr) is babysitting his grandson at his house in the Australian outback when a massive razorback boar attacks him, smashing through his house and dragging away his grandson to devour alive. Jake is accused of murdering the child and while his account of the events are met with high skepticism, he is acquitted due to lack of evidence. The event destroys his credibility and reputation however and he vows revenge on the boar.Two years later, American wildlife reporter Beth Winters (Judy Morris) journeys to the outback to document the hunting of Australian wildlife to be processed into pet food at a derelict factory. Beth gets video footage of two thugs, Benny Baker (Chris Haywood) and his brother Dicko (David Argue) illegally making pet food out of animals and is chased down by them by car. They catch up to her and attempt to rape her only to be chased off by the same boar that killed Jake's grandson. Beth attempts to take shelter in her car, but the hog rips off the door, lacerating her groin with its tusk before dragging her out to be eaten. With no witnesses, her disappearance is subsequently ruled an accident resulting from falling down an abandoned mine shaft after leaving her wrecked car.Some time later, Beth's husband Carl (Gregory Harrison) arrives in search of her and encounters Jake, whom Beth interviewed during her initial report. Jake refers him to the local cannery where he meets Benny and Dicko whom he convinces to take him along on their next kangaroo hunt, only to be abandoned by them when he spoils a potential kill. Carl is then attacked by a herd of wild hogs, spurned on by the giant boar, who chase him through the night and force him take shelter atop an abandoned windmill. The next morning, the hogs succeed in knocking over the windmill, but Carl is saved by landing in a pond at the windmill's base that is too deep for the hogs to cross over.Once the hogs leave, Carl attempts to make his way back to civilisation, all the while suffering from dehydration induced hallucinations before finally reaching the house of Sarah Cameron (Arkie Whiteley), a friend of Jake who has been tracking and studying the local hog population and the only one who believes his story of the giant razorback. While recovering at Sarah's house, Carl forms a friendship with her and learns that something has been causing the wild hogs excess stress, leading them into unusual behavior such as increased aggression and cannibalizing their own young. Meanwhile, after learning that Carl had seen the razorback, Jake sets out for the pumping station and manages to shoot it with one of Sarah's tracking darts. He also finds Beth's wedding ring in the boar's scat which he returns to a grieving Carl, who resigns himself to returning home.After overhearing a radio conversation suggesting that Jake knows what really happened to Beth Winters, Benny and Dicko, fearful that Jake is attempting to implicate them in her death, attack him at his camp, breaking his legs and leaving him to be killed by the razorback. His remains are later found by Sarah and Carl, along with marks in the dirt made by Dicko's cleaver. Realizing that the brothers were responsible for both his wife and Jake's death, Carl attacks Benny at his and Dicko's hideaway, interrogating Benny by lowering him into a mine shaft before letting him fall down it. As Sarah rounds up a posse to hunt down the razorback using the tracer Jake shot into it, Carl corners Dicko at the cannery when the razorback suddenly appears and mauls Dicko before Carl can shoot him. The razorback then chases Carl into the factory when Sarah suddenly arrives and is seemingly killed by the boar, who continues to pursue Carl even after being impaled through its throat with a broken pipe. In its maddened rampage, the razorback ends up damaging the cannery's generator which sends the machines running out of control as Carl lures the boar up onto a conveyor belt that throws it onto a giant fan, chopping it to pieces. After shutting down the machinery, Carl finds and rescues Sarah, who had merely been knocked unconscious, and the two embrace.
Output: Question: Whose wedding ring does Jake find in the boar's scat?, Answer: Beth Winters'
