On September 11, 2001, as information seeps out about the 9/11 attacks on the US, the FAA begins directing all remaining aircraft in the air to nearby airports, completely clearing the skies.

With wild rumours spreading, one British airliner's crew tells the passengers what is known, that a terrorist attack has taken place in the United States.

Personal stories emerge, with Mike Stiven (Shawn Ashmore), the air traffic controller at Gander meeting and falling in love with Alia Ramaswami (Anita Majumdar), a woman on one of the diverted airliners.

Of the total of 200 aircraft flying over the Atlantic at the time of the 9/11 attacks, 38 flights were diverted to Gander, bringing 6,600 passengers and crew to a town of 9,000.

Diverted was filmed during 2008 in the locations where the events occurred, including Gander, as well as St. John's, Newfoundland, Hamilton, Ontario, and London where many of the flights originated.
