在这部脑残粉剧情/动作/悬疑片中,高瑞夫（沙鲁克·汗 饰）是德里一个网吧的小老板，自小就是超级巨星阿利安•坎纳（沙鲁克·汗 饰）的疯狂粉丝，在他还在蹒跚学步之时就能模仿阿利安的舞蹈。然而“缘分真是如此奇妙，如此不可捉摸”，长大后的高瑞夫竟然长得一副阿利安的脸，随后在明星模仿秀节目中连连夺冠。马上就到阿利安的生日了，高瑞夫决定拿比赛奖金去圆自己一生的梦想——见偶像一面。于是他像阿利安当年一样，故意逃票去了孟买，住进了同一家旅店的同一间客房。为了达到见偶像目的，高瑞夫将对自己偶像出言不逊的某影星痛打了一顿，并以此作为送给阿利安的生日礼物，不料阿利安对此很生气并报了警……谁知此举导致了不可预见的后果，局势越发不可收拾。
In a world of labels it's easy to forget who made sportsmen, pop singers and matinee idols into stars, superstars and megastars - the FANS. Every FAN has their own personal relationship with their hero - it's almost a Love Story. FAN is the story of Gaurav (Shah Rukh Khan) a young man, 20 something, whose world revolves around the mega movie star Aryan Khanna (Shah Rukh Khan) or God as he refers to him. From the by lanes of Delhi, young Gaurav embarks on a journey to the city of dreams, Mumbai, in order to wish his God on his birthday. After all, he is Aryan's biggest FAN and even has a striking resemblance to him - how difficult could it be for the world biggest FAN to get an audience with the world's biggest Star. When things don't go according to plan, Gaurav's love and passion for his God turns in to a dangerous obsession that crosses the fine line. In an edge of the seat thriller, FAN will peel away at both Gaurav and Aryan's personalities and characters as the two men discover people within themselves that even they didn't know existed, and we're left wondering who to sympathize with and whom to root for - can we really pick a side, after all, Superstars are also human beings but each one of us is also a FAN.
