In a remote Australian outback community, Jake Cullen witnesses a massive razorback boar attack and devour his grandson, leading to a trial where his account is dismissed as incredulous. Devastated and seeking revenge, Jake becomes an outcast focused on hunting the ferocious beast. Meanwhile, American wildlife journalist Beth Winters arrives in the same area to document ecological concerns. During her investigation, she crosses paths with malevolent kangaroo hunters who do not take kindly to her presence. As Beth delves deeper into the local environmental issues, she disappears under mysterious and violent circumstances, prompting her husband Carl to travel to Australia to find her.

Carl's search brings him into contact with Jake, who reveals his own quest for vengeance against the monstrous razorback. As Carl uncovers more about the horrifying beast and the sinister activities of the kangaroo hunters, he becomes embroiled in a deadly struggle that intertwines the fate of the community, the wildlife, and the monstrous razorback itself. With danger lurking behind every corner and survival uncertain, Carl and Jake must navigate through a landscape marked by terror and chaos, driven by their own personal vendettas.
