In a godforsaken bar in the middle of nowhere, an all-girl band, Ms. 45, rips the stage apart with their punk spirit. But their performance impresses an enthusiastic fan who lures the girls into a trap, sedates them, and starts…customizing them. Slowly they begin to gain consciousness and, in total shock, realize their arms have all been replaced with axes and chainsaws to fight gladiator-style in a junkyard arena owned by a sadistic "emperor," forcing them into the battle of their lives with one prize in mind, their freedom.
