这一天是Jake与Evan在大学的最后日子，但他们对即将面对的现实生活世界非常害怕，因此，他们必须想法设法使自己留下来，在大学待上第五年…… On their last day of college, seniors Jake (Joel Paul Reisig) and Evan (Justin Isfeld) come to the realization that their days walking around in a drunken stupor and ogling half-naked coeds have ended. Fearing graduation and life in the real world, they hatch a plan to return for a fifth year. They enlist the help of "permanent" student and college legend Fossil (Johnny Lechner), who entrusts his sacred "Ten Commandments" on how to stay in college to Jake and Evan. Between antics from breaking into Professor VanOver's office (Christian Stolte) to kidnapping foreign exchange students, for Jake and Evan, this long day of debauchery is something they will never forget.
