The night before their high school graduation, four friends decide to celebrate their liberation with a road trip. When the group venture off the main road in search of excitement, things soon start to go wrong. They accidentally hit a bear cub and plough into a tree. And where there's a cub, there's a mother. Through the trees rampages one vengeful mummy bear.
With a swipe of a slashing paw one of the group, Ritch (Brody Harms), is shredded, leaving the remaining three to flee into the darkness. But with no help to be found, the trio have no choice but to find shelter, wait and hope.
However, they are not alone. The Grizzly is watching, waiting to take them on, one by one. How will Wes (Tyler Hoechlin), Sean (Graham Kosakoski) and Lauren (Kate Todd) escape?
