"The Happening" starts on a sunny day in Central Park. People are walking to work, exercising their pets, and generally going about the every day things they normally would. They're all interrupted however by a sweeping wind and a scream in the distance. Immediately afterwards, everyone in the park begins talking strangely, staring in the distance, walking backwards, and eventually killing themselves. Cut to a nearby construction site. A man falls from a high ledge he's working on, then another, then a gaggle all fall to their death as their comrades look on in horror.
