家财万贯的对冲基金经理詹姆斯（威尔·法瑞尔 Will Ferrell 饰）因为诈欺被判刑，法官特别给了他30天的时间让他安排处理工作上的相关事宜，身家百万的他为了准备好自己即将面对的恐怖监禁生活，雇用了平常帮他洗车的男子（凯文·哈特 Kevin Hart 饰），在最后自由的30天内对他加强训练，以应付之后的监狱生活……Kevin Hart plays the role of Darnell--a family man desperate to get enough money to buy a house in a better area to benefit his family's well-being. He is hired by James (Will Ferrell), a wimpy stock trader who is about to go to prison for 10 years, to prepare him for life behind bars. The catch is that James thinks Darnell is an ex-con--not because Darnell told him that, but because James just assumed.
