It's a movie-within-a-movie about jokes-within-jokes. Christopher Meloni stars as a low-rent producer determined to bring his vision to the screen. That vision entails a movie about the most offensive jokes ever told. Robert Klein and Mario Cantone sign up for the crew, and together they set out to pull off a hilarious and totally inappropriate scheme. In other words, it's loads of adult laughs from the company that took you on "Vacation" (1983) with Chevy Chase and back to school with "Van Wilder" (2002).
