Stu Shepard (Colin Farrell) is an arrogant New York City publicist who is contemplating cheating on his wife Kelly (Radha Mitchell). He calls Pam (Katie Holmes), a young actress, from a phone booth on a side street. When a delivery man (Dell Yount) tries to deliver a free pizza to the booth, Stu rudely dismisses him.
