Two heterosexual male friends Ben (Duplass) and Andrew (Leonard) meet after having not seen each other for 10 years. During a party, they find themselves locked in a "mutual dare" situation engaging to make a gay pornography, including anal sex, as an "art project" between two straight guys and submit it to the HUMP! (film festival). They do not decide yet who will penetrate whom. Ben tells Andrew that he will discuss the project with his wife Anna (Delmore). As Ben begins to describe the project to Anna, she reacts skeptically at the mere mention of amateur pornography. Ben finds himself lying to Anna; he talks about the project with only vague detail, telling her that he will likely act as a behind-the-scenes assistant to the hypothetical film crew.
