Jake Cullen (Bill Kerr) lives with his grandson in the Australian outback when a massive razorback boar attacks him, destroying his house and killing his grandson. He is accused of murder and his dignity is destroyed. Two years later, a wildlife reporter, Beth Winters, journeys to the outback to document the hunting of Australian wildlife to be used as animal food, processed in a large factory, but she is attacked by two deranged locals, Benny and Dicko, who leave her to be killed by the beast. Her husband, Carl, goes in search of her, and aids Jake Cullen and his young associate, Sarah Cameron, in hunting for the razorback responsible for her death. As they search for the creature, Benny and Dicko worry that they may be associated with the murder of Beth Winters, so they attack Cullen and leave him to be killed by the boar. Vowing revenge for his wife and his friend, Carl finds Benny and lowers him into a mineshaft, presumably killing him, and finds Dicko in the factory. Before he can kill him, the razorback surges and mauls Dicko to death before chasing after Carl and Sarah, where they face off inside the processing factory. Carl lures the Boar (having speared it with a pole) into pursuing him down a conveyor belt, at the end of which is a large industrial fan. Not able to stop itself, the boar falls to its demise onto the blade/fins killing it, while Carl rescues Sarah.
《猎魔》作为一部1984年上映的澳大利亚恐怖惊悚片，以独特的叙事视角和视觉风格，将观众带入了一场充满压迫感的自然反噬之旅。影片围绕一头巨型野猪在澳洲内陆引发的连环袭击事件展开，通过多线交织的叙事结构，逐步揭开人与自然冲突背后的残酷现实。
影片的角色塑造带有鲜明的功能性特征。主角卡尔·温特斯从一名追寻真相的丈夫逐渐转变为对抗自然威胁的战士，其动机虽缺乏深度心理刻画，但演员格雷戈里·哈里森的表演稳扎稳打，尤其在工厂与野猪对峙的高潮戏中，肢体语言和表情管理传递出强烈的紧张感。相比之下，女农场主莎拉·卡梅伦的形象稍显单薄，但其与环境的互动却成为推动剧情的关键纽带。配角如老猎人杰克·卡伦的悲情执念、野生动物记者贝丝·温特斯的理想主义悲剧，虽着墨有限，却在碎片化叙事中拼凑出人性在极端环境下的不同切面。
导演拉塞尔·穆卡希巧妙运用荒漠、戈壁与工业场景的视觉反差，构建出压抑而孤立的氛围。血色荒漠中的兽骨残骸、深夜突袭的猪群嘶吼，配合冷色调光影，将自然界的恶意具象化为一种原始而不可预测的力量。影片并未过度依赖血腥场面，而是通过环境细节暗示危险无处不在——例如废弃工厂中回荡的金属撞击声与野猪低吼的交织，营造出令人窒息的心理压迫。这种克制的表现手法，反而强化了恐怖氛围的真实性。
主题层面，《猎魔》跳脱了传统怪兽电影的娱乐框架，暗含对生态破坏的警示。人类对自然的掠夺性开发（如非法捕猎）与动物的生存反击形成因果闭环，使得“猎魔”不仅是人与野兽的对抗，更成为对人类傲慢的审判。值得一提的是，影片在澳大利亚本土上映时曾引发争议，部分观众认为其弱化了社会议题的探讨，但不可否认的是，它成功将地域特色转化为叙事优势，使偏远小镇的封闭环境成为人性试炼场。
总体而言，《猎魔》凭借扎实的惊悚节奏和富有隐喻的视觉语言，在B级片范畴内完成了一次类型突破。尽管角色弧光稍显模式化，但其对自然与人关系的尖锐质问，至今仍具有现实回响。
