伊根是个永不服老的惯偷。这次，刚从监狱出来，伊根就把以前的两个老伙计丹尼和凯德招集在一起，准备盗取哈里森用来向黑尔姆购买三万吨黄油的一千万美金。哈里森也是干这一行出身的，而且还是被国际刑警通缉的要犯。哈里森带着巨款一上岸就钻进了伊根精心设计的圈套，当哈里森驱车行至一家银行的门口时，伊根制造的一起银行遭抢劫案的假象引来了大批的警察。结果，在警察的眼皮底下，伊根从容地拿走了哈里森的钱箱。
得知伊根将钱箱保存在火车站的行李箱后，哈里森如法炮制，用同样的方法从伊根的车里拿走钱箱并伙同相关文件一起存入世界银行的金库。眼看到手的钱又得而复失，伊根并不甘心。他把凯德夫人的外孙乔治先生拉进自己的团伙，准备里应外合，从金库里将钱箱再偷出来。伊根带着两个伙计巧妙的混进了金库，在乔治的配合下，伊根拿到钱箱后顺利地逃了出来。没想到，哈里森此时已经等候在凯德家的附近，伊根刚回来就被哈里森打晕并劫持。
