The Photo Booth - I See You

People go into a photo booth to take pictures for fun and games, so they think. Some are able to take photos, and walk away. But, for those chosen ones, those who carries a dark secret, the outcome is a little different. Once their image is captured, that person's secret is exposed, and the photo booth seals itself from the inside. Preventing anyone from entering or exiting the booth until "Karma's work" is done.
