来自奥地利的布鲁诺(Sacha Baron Cohen 饰)是一档德语时尚节目的主持人,生活中他着装怪异前卫,大玩疯狂的同性恋游戏;荧屏中的他更加乖张出格,或诱导嘉宾说出争议性的言论,或干脆大闹T型台秀场。最终,他成名的愿望没有实现,反而被米兰的时装界所驱逐。一夜之间,布鲁诺的事业跌到谷底,连长久以来的同性恋人也琵琶别抱,最后只有忠心耿耿的第二助理鲁特兹(Gustaf Hammarsten 饰)陪其勇闯好莱坞。在洛杉矶,布鲁诺不改其张扬出位的本性,或为嘉宾奉上令人不忍卒睹的“男体盛”、或宽衣解带挑逗议员、甚至将自己的男性器官录进NBC的试播节目中。可想而知,嘉宾及电视台官员的脸色该有多难看。 屡战屡败,屡挫屡勇,百折不挠的布鲁诺为了扬名,在娱乐的道路上高歌猛进……Brüno is a gay Austrian fashion guru. He has his own fashion based television show, Funkyzeit, the most popular German-language show of its kind outside of Germany. After he disgraces himself in front of his Funkyzeit fan base, he is ruined in German speaking Europe. He decides that in his quest for worldwide fame, he will move to Los Angeles and reinvent himself. Accompanying him to the US is Lutz, his former assistant's assistant. Lutz is the only person left in his circle that still believes in Brüno's greatness. Brüno goes through one reinvention of himself after another, ultimately straying to areas far removed from his own self. Perhaps when Brüno finds an activity that he truly does love, he will also find that über-fame he so desperately desires.
