Jack and Grady are casual extras in the adult erotic movies made by WrinkleTheSheets productions. Since the day they were caught making out behind the catering trolley during the filming of Spurtacocks, their director Gerry has decided it’s safer and more entertaining to keep them on the payroll, even if their devotion -- and lust -- for each other makes them rather unreliable players. They support the darlings and divas of the company, from the vain Quinn to the surly Tomasz. They spend their time on cheap costumes and camoflauge, sex toys and phallic props, re-creating alternative classic movies in X-rated pastiches as never seen before. And throughout all the fun and banter, Jack and Grady’s modest love affair is a model of honesty and faithfulness. But Jack is beginning to have doubts. Grady's sex drive is generous and he’s always eager for novelty. Jack’s no longer sure he can satisfy that, worrying Grady is bored with him -- that Grady wants something else. If only Jack had the nerve to ask outright. Instead, he has to rely on uninvited and distinctly dubious relationship advice from his fellow actors. Why is Grady keeping secrets? Just what are the strange noises coming from behind the locked door of their shared trailer? And does poor Jack really want to find out?
