After 21st century serial killer Buster "Rant" Casey dies in a fiery blaze of glory, three of his closest compatriots--a gang of urban demolition derby aficionados affiliated with a group calling themselves The Party Crashers--travel back to his hometown of Middleton to record an oral history of their fallen idol.

But the question remains: "Who was Rant Casey?"
