Members of female punk rock band engage in a rowdy brawl with local hoodlums during their bar gig and spent the night at an auto repair shop with a kind passerby offering to fix their broken-down van. Upon waking up, they realize rather than getting their car fixed, they are in an arena made of junkyard cars and are mutated to be modern-day gladiators with mechanical parts replacing their limbs. Surrounded by blood-thirsty crowd and a local dictator named The Emperor, bloody battles ensue as they are thrown into the survival of their lives while they try to find the means to escape.
While travelling on their first American tour, Ms. 45, an all-girl punk band, is drugged and kidnapped. They awaken to find their limbs removed and replaced with crude weaponry, and are forced to fight as Gladiators for a sadistic town.
