GREENLAND 2: MIGRATION is the story of a family fighting for survival yet again. A comet named 'Clarke' has destroyed most of Earth. John Garrity (Gerard Butler), wife Allison (Morena Baccarin) and son Nathan (Roman Griffin Davis) managed to reach the underground bunkers near Thule Air Base in Greenland, in
time. They are joined inside by hundreds of survivors who hope to be out of the bunker once the effects of the comet pass. Sadly, five years pass and they are still holed up in the bunker as the region is rocked by sudden electromagnetic storms and radioactive fallout. Dr Amina (Amber Rose Revah) is a part of the core team, managing the bunker, and she reveals that, as per her understanding, the region in France, where the biggest piece of Clarke fell, is where life must have gone back to normal and the air quality and living conditions would be perfect. As they plan how to get there, a major earthquake collapses the bunker. John, Allison, Nathan and Dr Amina manage to escape in a lifeboat. The boat runs out of life and somehow they manage to reach Liverpool. From here, they decide to head to France and hope to rebuild their life in the crater site. However, several challenges lie in front of them. Firstly, the road from England to France is dotted with bandits and insurgents. Secondly, there's a belief that life at the crater site would be conducive to living; there's no guarantee about it. Lastly, John is terribly sick due to radioactive exposure. What happens next forms the rest of the film.
