Joe Dirt is a janitor with a mullet hairdo, acid-washed jeans and a dream to find the parents that he lost at the Grand Canyon when he was a belligerent, trailer park-raised eight-year-old. Now, blasting Van Halen in his jacked-up economy car, the irrepressibly optimistic Joe hits the road alone in search of his folks.

When happy family man Joe Dirt finds himself transported to the recent past, he begins an epic journey to get back to his loved ones in the present.
