John Garrity is a structural engineer living in Atlanta, Georgia, with his estranged wife, Allison, and their diabetic son, Nathan. He returns home from work to host a party with his neighbors and family to watch the passing of a recently-discovered interstellar comet named Clarke.

Arriving at a grocery store, John receives a strange automated phone call, informing him that he and his family have been pre-selected for emergency sheltering. Worried by this, John rushes home to the party, just as a comet fragment enters the atmosphere on live television. A shockwave rattles the area and blows out windows as the fragment, previously anticipated to land near Bermuda, vaporizes Tampa, Florida, and most of the state around it. John once again receives an automated call, which also displays on the television in front of his family and neighbors with instructions to be at Robins Air Force Base to make an evacuation flight. Terrified, their neighbors storm out of the house to be close with their families while the Garritys rush to pack up and leave. Before they can, their neighbor, Ed, warns them that Clarke is actually a giant cluster of objects that are expected to bombard Earth over the next two days, with the biggest fragment expected to cause an extinction level event. Debra, another one of their neighbors, desperately begs to leave their daughter Ellie with the Garritys to be saved, but John speeds off, knowing she would be turned away.
