The Carter family is part of this group of people. Fortunately, the wedding anniversary of Bob CarterLaVine) and his wife Ethel), who are just in time for the head of the family, is the best excuse to travel. Bob Carter is a police detective working for the Cleveland Police Department, known as "Big Bob". Having dealt with criminals and robbers all day, he has sharpened his rough lines and has a rough personality. But the wife who wanders around the pot and platform all day is a typical family woman, and she is constantly nagging about life trivial matters every day.
With the strong suggestion of the old couple, the big family is ready to embark on a car trip to the vast land of southwestern California. In fact, Big Bob also wanted to use this trip to enhance the affection and friendship between everyone in the family and eliminate the disharmony caused by friction in his past life. On the contrary, the eldest daughter Ryanworried that the long-distance trip will affect the health of her children, while the honest son-in-law Dau Bucuwiskybut always afraid of getting along with his carefree old father-in-law. At the same time, Carter’s youngest daughter Brendaalso hates this travel plan because it means that she will be separated from her close friends for a long time. But Bobby, the youngest son in the family, is full of longing for this long-distance trip, because he will be able to meet the two German shepherd dogs "Beauty" and "Beast" during the trip. There are more opportunities to play. Despite having different thoughts and comments about this road trip, the last family squeezed into Bob's old off-road vehicle and embarked on the journey to California together.
The car drove westward along the wide highway. In order to allow his family to enjoy the fascinating scenery of the west as soon as possible, Bob deliberately turned to a shortcut that he considered to be a shortcut. But after driving for a while, the Carter family discovered that they had completely entered a desolate and uninhabited area. There are yellow deserts everywhere, lifeless. After another distance, it was still deserted and deserted. And Bob's old broken car also made a mess at this moment and could no longer start driving. In the desolate desert, the Carter family has begun to realize that they have fallen into a great predicament.
When they were preparing to unite against this desolate "yellow killer", they gradually discovered that they were not the only survivors in this desolate land. Moreover, the Carter family also realized that they would face a more terrifying threat to their lives. A group of people who have also survived in the nearby mountains are slowly approaching the Carter family with strange eyes and strange behavior. These people seem to have survived in this barren zone for a long time, and have produced terrible mutations. Anything that can be eaten can arouse their unstoppable barbaric desires, and the blood-eating characteristics increase their level of terror. It turns out that this terrifying mutant is the offspring of the miners who used to work here. However, the nuclear weapons test site set up here by the unscrupulous US government at that time, after repeated nuclear explosion tests, people here have suffered various degrees of nuclear pollution, and it finally ended up in this situation. Right now, what the Carter family faced was how to escape the crazy attacks and killings of these barbarians, and how to return to the civilized world together.
