Tim Blake Nelson is a man who's safe and comfortable and bored to death with his life. In his state of despair, he looks to classic stories for inspiration. Awakened by the tales of yore, he anoints himself as Don Quixote to find adventure, fame and glory that will make his life worthwhile - all while never leaving his one-mile square neighborhood.

摇滚青年尼尔·唐斯（亚伦·斯坦福 Aaron Stanford饰）本来跟漂亮女友普斯·卡茨（佐伊·丹斯切尔 Zooey Deschanel饰）过着普普通通的日子。尼尔在一家燕麦饼干店里打工赚钱，他最大的梦想就是发行属于自己的唱片。而这家专卖燕麦饼干的小店老板，是一个老嬉皮士威利（克里斯托弗·洛伊德 Christopher Lloyd饰）。他每天热衷于搜集各种停产的燕麦饼干，花费大量的时间来制作，甚至跟别人谈论的话题也都是围绕燕麦饼干。 当大家都沉浸在这个温馨的燕麦饼干店中自得其乐时，街对面居然开了一家同样的燕麦饼干店，于是这平静的乌托邦生活被打乱了。
