Christine, Liz, Sam in Nick so štirje prijatelji, ki se nekega dne odpravijo na izlet v divjino. Njihova pustolovščina doživi preobrat, ko se jim sredi gozda pokvari avto in morajo prenočiti sredi divjine. Sredi noči jih obišče grizli, ki jim ga sicer uspe ustreliti, toda kaj, ko se prikaže še eden. Medtem ko četverica trepeta v avtomobilu, grizli počasi uničuje njihov avto. Samo vprašanje časa je, kdaj mu bo uspelo priti v avto. Panični prijatelji pa medtem prav tako pokažejo svoj pravi obraz.
Two young couples are driving through a remote forest when their car breaks down. When a run-in with a curious grizzly bear ends up with the bear being shot to death, the bear's mate arrives on the scene and vengefully attacks their van. The couples are trapped inside the disabled car and must come up with clever ways to survive. As they battle the surprisingly intelligent creature, and contemplate their uncertain fate, secrets begin to emerge that threaten to tear the group apart before the bear does.
