From the liner notes

One night, several deer inexplicably hurl themselves against the electric fence of a farm. Discovering deep bites on the animals' bodies, the farmer and visiting family members (who have gathered for a tense reunion) penetrate deep into the surrounding forest.

They carry guns, expecting to encounter wild predators, but what they are bewildered to find is an environment ravaged by a mysterious evil force. And as the sun slowly sinks away, howling resounds through the forest. The hunters have become prey!

This modern–day horror film blends elements of The Descent, Jaws, and Deliverance into an original picture of human nature scarier than the darkest woods.
