The Hills Have Eyes (2006)

While traveling in a trailer to California through the New Mexico Desert, a family is misled to a shortcut going to nowhere by the owner of an isolated gas station and wrecks the car in a rock. Along the night and on the next day, they are attacked by a group of deformed cannibals, fruit of the atmospheric nuclear tests conducted by USA from 1945 to 1962 in that spot. Absolutely trapped by the psychotics, they have to fight to survive.
