Will You Be Seeing Chappaquiddick [the movie] this weekend?

The Chappaquiddick incident was a single-vehicle car accident that occurred on Chappaquiddick Island, Massachusetts, on Friday, July 18, 1969. The late night accident was caused by Senator Ted Kennedy's negligence, and resulted in the death of his 28-year-old passenger, Mary Jo Kopechne, who was trapped inside the vehicle.

According to his own testimony, Kennedy accidentally drove his car off the one-lane bridge and into a tidal channel. He swam free, left the scene, and did not report the accident to the police for ten hours; meanwhile, Kopechne died inside the fully submerged car.
