In New York City, Sonny Koufax is a 32-year-old slacker and law school graduate who hasn't taken the bar exam, works one day a week as a toll booth attendant, and lives off a $200,000 compensation from a minor accident which he was involved in two years prior to the events of the film. His girlfriend Vanessa threatens to break up with him unless he takes more responsibility. His roommate Kevin Gerrity proposes to his podiatrist girlfriend Corinne before he leaves for China to work on a case for his law firm and she accepts. Corinne vehemently dislikes Sonny because he constantly teases her about her former job at Hooters when she was in medical school.
