Peninsula (2020)

A zombie outbreak overwhelms South Korea, prompting international evacuations before the peninsula is quarantined in Busan. ROKMC officer Jung-seok flees aboard an evacuation ship with his sister, her husband Chul-min, and their young son Dong-hwan. He refuses to help a distressed family after noticing the father is bleeding. An infected passenger soon turns into a zombie and bites several people, including Dong-hwan. Jung-seok's sister remains behind with her son and is bitten; Jung-seok seals the cabin, preventing Chul-min from reaching them as soldiers intervene.

Four years later in Hong Kong, Jung-seok, Chul-min, and two other Korean refugees are recruited by Chinese mobsters to return to South Korea and retrieve a truck containing US$20 million, in exchange for half the money. They locate the truck at night and kill its zombie driver, but the noise attracts a horde. While escaping towards Incheon Port, they are ambushed by a rogue militia squad from Unit 631, led by Sergeant Hwang. Their vehicles crash, killing one team member; Hwang kills another. Chul-min hides in the truck while Jung-seok flees and is rescued by sisters Joon-yi and Yu-jin. They take him to their hideout, where they live with their mother Min-jung and grandfather Elder Kim, who believes his military friend Jane will respond to his radio transmission. Jung-seok realises that Min-jung and Yu-jin are the mother and daughter he refused to help four years earlier.

Unit 631 takes the truck to its base, unaware of the money inside, and forces Chul-min into a survival game against zombies. Private Kim discovers the money and informs Captain Seo, who secretly contacts the mobsters and plans to escape the peninsula alone. Jung-seok tells Min-jung that an extraction ship awaits at Incheon, prompting her to devise a plan to steal the truck and escape with her family and Jung-seok.

That night, Jung-seok and Min-jung infiltrate the militia base. After learning from Private Kim that Chul-min is alive, Jung-seok interrupts the survival game to rescue him. Chul-min saves Jung-seok from a zombie bite but is shot dead by Hwang. Min-jung escapes with Jung-seok in the truck, but a zombie horde blocks their route. Joon-yi, Yu-jin, and Elder Kim arrive and distract the zombies with their car, enabling both vehicles to escape. Hwang and Unit 631 pursue them, but their vehicles are destroyed and Hwang is killed by zombies.

At Incheon Port, Seo kills Private Kim, ambushes the family, and takes Joon-yi hostage. Yu-jin distracts him, allowing Joon-yi to escape, but Elder Kim is fatally shot and Min-jung is wounded. Seo reaches the extraction ship with the truck, only for the mobsters to betray and shoot him. Before dying, he reverses the truck into the cargo ramp, allowing zombies to overrun the ship and kill everyone aboard.

Jung-seok and the family signal a passing U.N. Chinook, which responds to Elder Kim's radio transmission. Min-jung stays behind to hold off the zombies while Jung-seok and her daughters reach the helicopter, intending to shoot herself afterwards. Remembering Chul-min's regret over failing to protect his family, Jung-seok returns for her and kills the pursuing zombies. Min-jung escapes, and the family safely boards the helicopter and evacuates the peninsula. The rescuing soldier's name tag shows "Jane", meaning elder Kim wasn't hallucinating or fabricating his story about the UN rescue.
