Despite their insistence that they would not let sex with each other affect their friendship, Zack and Miri soon develop romantic feelings for each other. When it comes time for Zack and Miri to have sex on camera, they find that instead of the clinical sex enacted by the actors in the other scenes, their interlude is romantic and heartfelt. Later the next evening, Zack and Miri are at home tentatively about to discuss their reactions to the scene, when suddenly their apartment's electricity and water service return. The rest of the actors and crew reveal that they pooled their resources to pay one month of Zack and Miri's bills and are throwing them an early wrap party.
