Four years after a deadly virus transformed most of South Korea into a zombie wasteland, Jung-seok lives a solitary life as a scavenger in the ruins. Haunted by past trauma, he’s lost all hope. But everything changes when he’s reunited with his estranged sister, Min-jung, who has a glimmer of hope. They encounter Captain Lee, who offers them passage to Hong Kong in exchange for a daring heist back in Korea. Venturing back into the infected peninsula, Jung-seok and Min-jung must confront nightmarish evolved zombies, ruthless scavengers, and their own inner demons to survive and find redemption.
