-Beginning with these two hikers, one of them showing the other this beautiful spot, a cliff over a lake, they then hear something before the bear comes out of the bushes and kills them.
-As the father and children are driving to the location, the radio talks about the two missing hikers, which had happened to occur around the same area, telling campers to be cautious.
-Upon setting up camp and settling down, they hear noises from the bushes but before they can find it, whatever caused it disappeared.
-The following night after roasting marshmallows and going to sleep, they hear the noise again and the sounds of stuff dropping, thinking its a grizzly bear, the father tells his children to stay quiet as a shadow of the short-faced bear can be seen through the tent, after a few moments, it disappears.
-The next day, they go fishing with the father teaching them how to, while doing so they come upon the mauled body of a grizzly bear which the father assumes was the result of another grizzly.
-As they return, they find their camping area completely destroyed, tent was torn up, food everywhere, stuff all over the place, if that's not the worst of all, the fathers truck has been heavily damaged beyond repair, claw marks all over it and the tires destroyed, leading to the father to think it was the grizzly bear the following night.
-With no help of any other campers nearby or wifi, he and his children go looking for other campers who could be in the area, as they do this, they begin to hear the bear following them, the father tries to scream and yell to scare it away but to no avail and assures his children will be okay.
-As they continue to search for help, they finally encounter the bear who had caught up to them but to their surprise is not like any grizzly bear known and rather bigger with a short face with white markings and longer legs, as it draws closer and realizing staying still isn't helping, the father tells his children to run as they try to get away as fast as they can.
-Night falls and thinking they had lost the bear, the children begin to cry being scared about the situation, the father comforting them and that they'll make it out of this, as they proceed, the bear can be heard again forcing them to get away quicker, they narrowly avoid the bear again, catching a brief appearance of it again.
-They come upon a grisly sight, upon catching an awful stench, underneath some grass and leaf material is not only the carcass of and dead moose but those of the two missing hikers as well. The father gets his children not to look.
-Exhausted from running all night, he and his children continue to hear the bear keeping up with them, having slowly stalked them taking its time, with no other options, they proceed to hide somewhere with the father making the hard decision to sacrifice himself (Wielding a camp knife) and fight the bear after finding a place to hide his son and daughter telling them to stay where they are and that he loves them very much despite their pleas to him not to go, as he goes to face the bear, his children hear him scream at it to take him on, a brief fight is heard soon following the cries of agony and pain from the father as the bear proceeds to kill him off-screen.
-The epilogue goes on to reveal when he and his children had never returned from their camping trip that a search party was put in place eventually finding the children who are clearly traumatized and brought back to their mother and though his body was never found aside from blood on the ground, the father's cause of death is listed as a grizzly bear attack with the search for the bear but it was nowhere to be found afterward.
