In California, Nick decides to take a shortcut while driving his van to a steakhouse to celebrate his parents' anniversary with his girlfriend Christine, his estranged brother Sam and his wife Liz. Nick has a flat tire and a grizzly bear threatens the group, but Sam discharges his pistol against it. When they are ready to go, the bear's mate attacks them, capsizing their van. During the night, they are trapped in the van and secrets are disclosed while they are attacked by the vengeful animal.
