This episode gets its scenario from an in-joke in the website. The episode is actually the "film" Dangeresque 3. He invites his friends over to his basement for the film's premiere. The player then assumes the role of Dangeresque, embracing the cliches and tropes of the action film genre, with the movie looking like a very low budget film.
