Having narrowly avoided prison following the antics of the previous film, Nick (Bateman), Kurt (Sudeikis), and Dale (Day) decide to go into business for themselves. When their breakthrough product, the Shower Buddy, catches the attention of a wealthy entrepreneur named Bert Hanson (Christoph Waltz) who offers to bankroll their initial production run, the eager inventors quickly move into manufacturing. Proudly filling Hanson's initial order before the deadline, they decide to surprise their key investor with the good news, only to get a nasty surprise: A shrewd businessman with a serious lack of ethics, Hanson announces that he is canceling the deal. With no investors to keep the business afloat, the Shower Buddy factory will soon fall into foreclosure, allowing Hanson to scoop up the product at a fraction of the original cost, change the name, and reap the profits. Indignant, Nick, Kurt, and Dale hatch a plot to kidnap Bert's son Rex (Chris Pine) for a healthy ransom, paying a visit to criminal mastermind Dean Jones (Jamie Foxx) for a few pointers on the fine art of abduction. Needless to say, nothing goes quite as planned, and as the police launch an investigation into the elaborate crime, the hapless trio must once again race to stay one step ahead of the law..
