Seth and Evan, along with their friend Fogell (Christopher Mintz-Plasse), spend the vast majority of the movie getting into and out of trouble as they try to obtain liquor. Along the way they encounter a menagerie of loons, including two police officers played by Seth Rogen and Bill Hader. The officers end up traveling around with Fogell, who is going under the name "McLovin" as that's what his fake ID reads, and prove that being an officer of the law can be fun (provided you wreck your police car and drink on the job).
The DVD is currently available as a two-disc set. It comes with several different behind the scenes looks at the movie, from table reads to casting sessions and on-set diaries. There are also extended and deleted scenes, a look at the music in the movie, a gag reel, and a look at the filming of the dancing in the opening credits (among other things). One of the funniest special features included is a mockumentary "Everyone Hates Michael Cera – The Unfortunate True Story" which features Cera being obnoxious and everyone complaining about him.
