Peninsula (Korean: 반도; Hanja: 半島; RR: Bando; marketed internationally as Train to Busan Presents: Peninsula) is a 2020 South Korean post-apocalyptic action horror film co-written and directed by Yeon Sang-ho.^[4][5]

It is a standalone sequel to the 2016 film Train to Busan, the second live-action feature film and the third overall installment in the Train to Busan film series. The plot follows a former soldier who is sent along with a team to retrieve a truck full of money from the wastelands of South Korea, now inhabited by zombies, rogue militia, and a family. The film stars an ensemble cast featuring Gang Dong-won and Lee Jung-hyun

Peninsula was chosen to premiere in the 2020 Cannes Film Festival, which was cancelled due to the COVID-19 pandemic, and simply released theatrically in South Korea on 15 July 2020, while also being shown at the 25th Busan International Film Festival on 21 October 2020. It grossed $42.7 million worldwide on a $16 million budget but received generally mixed reviews from critics, who found it inferior to the first film.

South Korea is being overrun by a zombie outbreak,^[a] and many countries are evacuating survivors before quarantining the peninsula in Busan. ROKMC officer Jung-seok drives his sister, her husband Chul-min, and their young son Dong-hwan to an evacuation ship. On the way, they encounter a distressed couple with a young daughter, but Jung-seok refuses to help them after noticing the man bleeding. They board the ship, but an infected man turns into a zombie and bites several people in their cabin, including Dong-hwan. Jung-seok’s sister refuses to leave Dong-hwan, and he is forced to close off the infested cabin as zombies bite her, preventing Chul-min from entering as armed soldiers arrive.
