Carly and Freddie decide to spy on Ms. Briggs and show it on iCarly. To avoid being caught, Carly and Freddie hide in Ms. Briggs' closet. When she catches them, she makes a compromise with them: she won't call the police if they let her play the bagpipes on iCarly. At first, her bagpipes cause iCarly to lose viewers, but then they test out the newly installed green screen behind Ms. Briggs, bringing back their audience.
