About Man's best friend turns against him when a horde of bloodthirsty wild dogs descends upon a family's farmhouse. In a remote stretch of the Australian Outback, a sheep rancher, his veterinarian wife, and their two teenage children live in bucolic isolation-until a horrifying night when a pack of fang-bearing, four-legged rabid beasts besiege their home. With no one around to help them, the family must band together to survive-or else become canine kibble. Generating a steadily mounting sense of dread, this film cleverly toys with genre conventions before it goes in for the kill.
