A female punk rock band finds themselves in a chaotic fight with local troublemakers during a bar performance. Afterward, they end up spending the night at an auto repair shop, where a friendly stranger offers to fix their broken-down van. However, when they wake up, they discover that instead of having their vehicle repaired, they have been transported to an arena constructed from junkyard cars. They have been transformed into modern gladiators, with mechanical parts replacing their limbs. Surrounded by a bloodthirsty audience and a local tyrant known as The Emperor, they are forced into brutal battles for survival as they desperately seek a way to escape.
