成为约翰·马尔科维奇

戈尔（约翰•库萨克 John Cusack 饰倒的木偶艺人，善于操作舞台上傀儡木偶。生活所迫，他进入了一间纽约一间公司从事文件管理工作。这间公司在办公大厦的七楼半，由于它只有半层楼高，所以职员们都只能拱着腰工作。 　　正是由于这样，戈尔偶然发现了公司的文件柜后面有一扇门。好奇心驱使下，戈尔进入了这扇门。当戈尔一进入门内，马上便被吸入了其中，并飞越时空进入了著名演员约翰.马尔科维奇的大脑中。他发现现在自己能随意控制约翰.马尔科维奇的目光，并窥探到一切约翰.马尔科维奇的私隐。十五分钟后戈尔自动被弹回了现实中。 　　这一发现令戈尔兴奋不已，他决定利用这扇门做一笔大生意。Puppeteer Craig Schwartz and animal lover and pet store clerk Lotte Schwartz are just going through the motions of their marriage. Despite not being able to earn a living solely through puppeteering, Craig loves his profession as it allows him to inhabit the skin of others. He begins to take the ability to inhabit the skin of others to the next level when he is forced to take a job as a file clerk for the off-kilter LesterCorp, located on the five-foot tall 7½ floor of a Manhattan office building. Behind one of the filing cabinets in his work area, Craig finds a hidden door which he learns is a portal into the mind of John Malkovich, the visit through the portal which lasts fifteen minutes after which the person is spit into a ditch next to the New Jersey Turnpike. Craig is fascinated by the meaning of life associated with this finding. Lotte's trips through the portal make her evaluate her own self. And the confident Maxine Lund, one of Craig's co-workers who he tells about the portal if only because he is attracted to her, thinks that it is a money making opportunity in selling trips into Malkovich's mind after office hours for $200 a visit. Craig, Lotte and Maxine begin to understand that anyone entering the portal has the ability to control Malkovich's mind, which also alters his entire being. This experience makes Maxine fall in love with a composite. This ability to control Malkovich's mind begs the question of the ultimate psychedelic trip for Malkovich himself, who begins to feel that something is not right in the world as he knows it.
