Goodbye Earth

The series follows the final 200 days before an asteroid is expected to collide with Earth on February 22, 2026. South Korea has been placed under martial law following an outbreak of violence and an attempted coup since the announcement of the asteroid's approach. Many wealthy citizens have fled the country to supposed safe zones, and remaining residents have to deal with hopelessness, reduced supplies, widespread suicide, rampant crime, and various scams offering supposed salvation. In the city of Woongcheon, four friends struggle with the changed circumstances: Jin Se-kyeong, a former teacher who works as a volunteer at city hall; Dr. Ha Yun-sang, Se-kyeong's scientist fiancé who was stuck in the US during the riots; Captain Kang In-a, an army captain trying to control her support unit; and Father Woo Sung-jae, an assistant priest who has to take charge of the parish when the main priest disappears. Se-kyeong is involved in the lives of her former students, and learns about a human trafficking ring run by escaped convicts, who kidnap children and were responsible for the deaths of many of her students. Kang In-a's investigation leads her to the same group, as the escaped convicts are working together with discharged soldiers to run gambling dens and brothels. The crime rings are connected to a cult-like elitist group that is gathering funds to buy their escape to another country. Sung-jae faces a crisis of faith when he learns that his superior, Father Baek, is part of this elitist group and absconded with church funds to join them. Yun-sang has the opportunity to join this group and bring Se-kyeong with him, as he is a geneticist whose research will be important for humanity's post-asteroid survival, but he refuses to leave without Se-kyeong, who refuses to abandon her former students. The four friends and their allies learn that the elitist group have arranged for two planes to pick them up for a last chance to escape South Korea. Se-kyeong, Yun-sang and Sung-jae attempt to negotiate for the children to be allowed to leave, but are unsuccessful. However, one plane is unable to land due to protests on the emergency landing strip, and the other plane crashes en route, killing all aboard. In the last remaining days before the asteroid's arrival, various residents try to find peace, settle unfinished business, or fall into despair. Se-kyeong and Yun-Sang get married but are troubled by what they have learned about each other. Yun-sang runs a memorial project to document as much of Woongcheon and its residents for possible future visitors. In-a is discharged from the army and drives off to be on her own. Sung-jae leaves the priesthood but continues to care for the community. Se-kyeong is still tormented by the loss of her students and, upon learning that criminals have resumed trafficking children, goes to their gambling den with a gun to kill them.
