Jerry (Jack Black) is a junkyard worker who attempts to sabotage a power plant he suspects of causing his headaches. But he inadvertently causes his brain to become magnetized, leading to the unintentional destruction of all the movies in his friend's (Mos Def) store. In order to keep the store's one loyal customer, an elderly lady with a tenuous grasp on reality, the pair re-create a long line of films including The Lion King, Rush Hour, Ghostbusters, When We Were Kings, Back to the Future, Driving Miss Daisy, and Robocop , putting themselves and their townspeople into it. They become the biggest stars in their neighbourhood.
