Greenland (2020)

John Garrity is a structural engineer living in Atlanta, Georgia, with his estranged wife, Allison, and their diabetic son, Nathan. He returns home to watch the near-earth passing of a recently-discovered interstellar comet named Clarke, with his family and neighbors. While in a store, John receives a strange automated message from DHS informing him that he and his family have been selected for emergency sheltering. Confused and concerned, he returns home just as a comet fragment enters the atmosphere on live television. Previously expected to land near Bermuda, the fragment instead strikes Tampa, Florida, vaporizing the city and most of the state. John once again receives a call with instructions to head to Robins Air Force Base for an evacuation flight. The Garritys then learn from their neighbor Ed that comet Clarke is on a direct collision course with Earth, and the entire planet will be bombarded with hundreds of fragments within the next two days in a cataclysmic event, with the largest fragment expected to cause an extinction level event. The family packs up and flees, unable to take anyone else, as they would be denied boarding.

At Robins, while consolidating their belongings into one bag, the family discovers that Nathan’s insulin was left in the car. John hurries back for it, while Allison and Nathan are told that they cannot board because of Nathan’s diabetes, and are then escorted off the base. Realizing what happened, John leaves the base as a panicked mob breaks in, destroying several evacuation planes when gunfire ignites jet fuel. Returning to their car, he finds Allison’s note that they left for her father’s in Lexington, Kentucky. After getting medical supplies from a looted store, Allison and Nathan are picked up by Ralph and Judy Vento. Against Judy’s objections, Ralph kidnaps Nathan, hoping to use him and the wristbands to board a flight.
