After a suspicious lunch, two friends complain about the excess of gas that afflicts them. When one of them accidentally lets out a loud fart, the other calls her “disgusting” and turns her face away with contempt. Furious at the reaction, the offended friend decides to teach her a lesson: she grabs the critic by the arm and forces her to smell each of her farts as a form of domination. What begins as a clumsy joke turns into a power game, where embarrassment and humor mix - until the roles are reversed, and revenge arrives with a final and unexpected finish.
