Beanie suggests that they form their own fraternity in Mitch's new house on a college campus to re-live their glory days by bringing together a variety of misfit college students, losers, middle-aged and elderly retirees as their new friends and later try to avoid being evicted by the new Dean of Students, Pritchard, whom still holds a personal grudge against all three of them.
