Richard is a L.A. used car salesman on a quest to find the true meaning of his life. When he turns over his car lot to his inept assistants, he begins to write his first screenplay -- a woeful tale about a truck driver who runs over a little girl and gets shot to death trying to outrun the law. When Mammoth Pictures shows interest in the script, he must scramble to get it made, enlisting an assortment of oddball characters, including his washed-up, ex-filmmaker father, his lustful stepsister and his pregnant secretary, as his crew.
