Peninsula is a 2020 South Korean action-horror film directed by Yeon Sang-ho. It is a standalone sequel to the 2016 film Train to Busan and follows a soldier who is sent along with his team to retrieve a truck full of money from the wastelands of the Korean peninsula now inhabited by zombies, rogue militia, and a family.
Peninsula was chosen to be shown in the Official Selection of the 2020 Cannes Film Festival, which was cancelled due to the COVID-19 pandemic. The film was shown in the Panorama section of 25th Busan International Film Festival on October 21, 2020.
The film was released in South Korea on 15 July 2020. It received mixed reviews from critics and has grossed $42.7 million worldwide.
Republic of Korea Marine Corps Captain Jung-Seok is driving his elder sister, his nephew Dong-Hwan, and his brother-in-law Chul-min to a ship to escape a zombie outbreak in South Korea. On the way, he encounters a family with a young child, but he ignores the family's pleas for help and keeps driving. Later, in the cabin of the ship, an infected man turns into a zombie and infects numerous people, including Dong-Hwan. Jung-Seok's sister refuses to leave her son, so Jung-Seok is forced to block everyone, including Chul-min, from accessing the cabin.
Four years later in Hong Kong, a guilt-ridden Jung-Seok and Chul-min are recruited by Chinese mobsters for a mission with two other Koreans to return to the quarantined peninsula and retrieve an abandoned food truck which contains US$20 million in bags; if successful, they would receive a split of half of the money. The team arrives at the peninsula at night by boat and soon find the truck. After the zombie driver wakes up, the horde is lured to a sound of a horn and activation of car alarm systems, sending the team to escape with the truck as zombies began chasing them.
On the way back to Incheon Port, they are ambushed by a rogue militia Unit 631, led by Sergeant Hwang. Jung-Seok is thrown out of the truck and Chul-min hides inside. The two other members of the team are killed, one as a result of the crash, and one by Sergeant Hwang. Jung-Seok is rescued by two sisters: Joon and her younger sister Yu-Jin. Joon drives to a hideout where the children live with their grandfather Elder Kim and mother Min-Jung - the latter, Jung-Seok realizes, who is the lady who pleaded for his help four years ago.
Meanwhile, the Unit 631 soldiers take the truck to their compound and imprison Chul-min upon discovering him in the back, forcing him to take part in a series of timed survival games between prisoners and the infected. Private Kim and Captain Seo discover the cash in the truck and secretly hatch a plan to escape the peninsula with the truck, keeping their plans a secret from Sgt. Hwang and the rest. Meanwhile, Min-Jung learns from Jung-Seok that there is a ship at Incheon Port waiting to extract him and the truck. She decides to steal the truck from the compound so that the five of them (her family and Jung-Seok) can escape.
