Gorgeous IRA operative Marie flees the British authorities and finds herself somewhere in the American continent, where she meets a stunning woman also named Marie, a singer in a traveling circus. The new friends start a vaudeville act that grows exponentially more popular after they incorporate striptease into their routine. When the singer Maria falls for a charismatic rebel, the girls leave the circus behind and recreate themselves as wild-eyed revolutionaries.
