When a mysterious comet passes close to Earth, machines everywhere suddenly take on murderous minds of their own. Soon, video games, cash machines, drawbridges, and steamrollers all go on a psychotic killing spree of global rebellion. But when the Dixie Boy Truck Stop is held hostage by a mob of homicidal 18-wheelers, human vengeance goes into overdrive. Who made who? And who will survive the final showdown of man vs. bloodthirsty machine? Emilio Estevez stars in this outrageous, twisted metal epic that marked the directing debut of horror master Stephen King and features a headbanging score of classic hits and original music by AC/DC.
