Facing the conflict caused by greed, the characters who were originally scattered will gather together again: Cha Hyun-soo (played by Song Kang) wakes up and finds that he has become a monster; Byun Sang-wook (played by Lee Jin-wook) whose body is occupied by Zheng Yiming; Seo Yi Kyung (played by Lee Shi-hyun) became half-human and half-monster; Lee Eun-hyuk (played by Lee Dae-hyun) emerged from the violently shaking monster cocoon; Lee Eun-you (played by Ko Min-seo) persevered and continued to search for his brother Eun-hyuk;Private Park Chan-young (played by Jung Jin-young) returns to the field; Sergeant Tak In-hwan (played by Yoo Oh-sung) still hides the fact that he has symptoms of monster transformation; Dr. Im (played by Oh Jung-se) has shown unusual interest in monster transformation; Kim Young-hoo JungA soldier (played by Kim Moo-yeol) meets new survivors on Yuldo Island; and a girl (played by Kim Seil-ah) who has the ability to turn other people into monsters appears.

The third season tells the story of the end of monsterization and the birth of new humans. Between the blurred boundaries between monsters and humans, they are at a crossroads of choices, a more desperate situation and a story of their struggle to survive.

In the latest official poster, Hyun Soo (played by Song Kang) walks towards the devastated city center and faces the unresolved crisis of monsterization.The sight of Hyun-soo spreading his monster wings makes one wonder whether he can regain his human self after being overrun by monsters at the end of season two.

Several cocoons growing on the ceiling and the mysterious species shining inside them hint that a new era of mankind is coming, and echo with the text on the poster “All evolution is complete”, triggering fans of the show to start the third season.Very curious about the new story.
