Peninsula (2020) Timeline Explained – Every Event in Order

Jung-seok spots a bleeding wound on the husband's arm. Recognizing this as an early sign of zombie infection, he refuses to let them onboard because he knows the bite will turn them into a walker. This decision haunts him throughout the film when he later discovers the mother and daughter he abandoned are the same family he encounters years later.

Foreshadowing: The husband's wound is briefly visible as he pleads for help, establishing Jung-seok's initial hard choice.

Jung-seok and Chul-min are living as refugees in Hong Kong when Chinese mobsters recruit them for a dangerous mission.

Joon-yi and Yu-jin are the mother and daughter Jung-seok refused to help during the original evacuation four years earlier. Yu-jin was the young daughter begging for a ride.

Sergeant Hwang's rogue militia forces captives like Chul-min into brutal games where they must fight waves of zombies with minimal weapons.
