The movie begins with the nation of the Sun going out, and people struggling to survive due to the loss of solar energy. The main character, Yang, discovers that the sun's luminosity has decreased by 15% and will continue to drop. He decides to travel to District 4, which has geothermal energy, in search of a way to survive.
Along the way, Yang meets a woman named Chemo, who joins him on his journey. They face various obstacles, including encounters with desperate and violent people, and eventually arrive at District 4. However, Yang is shot and injured, and their car runs out of battery and oxygen.
Just as all hope seems lost, they are rescued by a couple they met earlier in the movie, who take them to a geothermal sanctuary. The movie ends with a voiceover revealing that the survivors are building geothermal sanctuaries and that the Earth is moving to a new solar system with three suns.
