In a small, quiet town, a lonely young man named Arnie Cunningham discovers what seems to be the opportunity of his life: a classic car, a 1958 Plymouth Fury. However, this is not an ordinary vehicle; it is possessed by a dark and malevolent force that will soon begin to influence Arnie's life in inexplicable and terrifying ways. At first, the car appears to give him confidence and a newfound sense of belonging, transforming the shy boy into someone more self-assured and drawn to a carefree lifestyle.
As Arnie becomes obsessed with his new car, his personal relationships start to deteriorate. His best friend, Dennis, and his girlfriend, Leigh, become increasingly concerned about his metamorphosis and the way the vehicle is controlling him. Meanwhile, the car begins to display violent behavior, disposing of those who threaten its relationship with Arnie. What started as a mere object of desire quickly spirals into a nightmare, with an aura of vengeance that leaves a trail of destruction.
Amid a climate of tension and a cast that exudes an air of psychological horror, the story explores themes of possession, obsession, and the struggle between friendship and madness. The lives of those around Arnie are about to change forever as the malevolent car becomes a symbol of his deepest fears.
