The entire plot of the movie is told in a rap song during the opening credit:
Well John's the lead in this meaty scene
He's the Candyman, if you know what I mean.
And he drives a long black limousine
With his sidekick Chick! [car horn sound]
Now John's the drummer out in the street,
But the man can't even keep a beat
So he spins his wheels to make ends meet.
You got it? [Woman's voice: "Huh?"] Stay with me now!
John's got a pretty little fiancée.
When her daddy's trying to pull a power play,
And if Big Daddy gets his way,
Our man John will be wearing cement shooooooes!
