To celebrate their wedding anniversary, the elderly couple Bob Carter (Ted Levine) and Ethel (Katherine Quinlan) took their family on a long road trip across the border. They hoped to enhance the relationship between family members through this trip, but the frictions that occurred during the trip tested the family from time to time. The journey gradually entered the endless yellow sand deserted area. When they were resting during camping at night, they were attacked by a group of monsters. It turned out that there was an abandoned base for the development of nuclear weapons by the US military nearby. The nuclear experiments caused the people in a nearby village to suffer terrible nuclear radiation. The people who survived became deformed and bloodthirsty and violent. They ambushed the family and brutally hunted them. The originally honest and cowardly son-in-law Davu Bukuwiski (Aaron Stamford) was determined to cheer up and make the strongest counterattack.
