　　影片的男主角基顿（巴斯特·基顿BusterKeaton饰）是一名乡村影院电影放映师，他喜欢阅读侦探类的书籍，经常幻想自己就是一名像福尔摩斯一样的大侦探。一天，他把价值一元的巧克力糖谎称四元送给女友凯莎琳（KathrynMcGuire饰），不料被情敌趁机陷害，说基顿偷了别人的手表拿去当才有钱买巧克力。凯莎琳相信了谗言，遂将基顿赶出门外，并取消了二人之间的婚约。基顿查访之后，发现情敌才是偷表典当的家伙，但却苦无证据洗清冤情。某日，基顿在放映电影时，发现银幕上的故事竟和他的遭遇同出一辙，而且人物也雷同，唯一不同的是电影中的故事发生在一个上流家庭而已。基顿边放映电影边沉溺在电影之中，于是走出放映室，从观众席走入银幕之中逮捕情敌罪犯。可是进入银幕后的基顿却四处碰壁，一筹莫展．随着场景的变化，银幕上的映象不断从幻想变成事实…eee
