Zombie Strain

On the night just before Christmas, in the midst of the COVID-19 pandemic, two men in Seoul break into a container from China containing gold jewelry. But also in the container is a cat, which suddenly attacks and scratches one of the men. Later, as they retreat, the scratched man, Wang-i, becomes sick. When his concerned friend looks after him, Wang-i suddenly attacks him and bites his throat out before rolling into the nearby river. He floats in the current to the Gangnam District, where he emerges from the water and later catches public attention by consuming a chunk of raw, bloody meat in the streets. Hyeon-seok, a former taekwondo champion, has recently moved to Seoul for work at a small online streaming firm in a Gangnam office building. He has a crush on his co-worker Min-jeong, but Min-jeong disapproves of him, while his carefree, selfish boss Tae-soo harasses her and has yet to make any profit and pay his workers a salary. The next day, Wang-i appears in the building and attacks people, who swiftly turn into blood-craving zombies like him and bite any human being they encounter, rapidly spreading the infection. Soon-ja, the building's renter, orders the exits to be locked, sealing everyone inside, before she and a wounded security guard are forced to flee to Hyeon-seok and Min-jeong's workplace and inform them of the situation. Smelling a chance for profit, Tae-soo insists on filming the carnage, but the group is discovered and attacked, and all but Hyeon-seok and Min-jeong are killed and infected. Unable to call for help because the phone lines are blocked, they try to fight their way out but are eventually cornered in the entrance hall. Hyeon-seok shelters Min-jeong inside a minivan before reentering the fight. Just as he is being overwhelmed, Min-jeong rescues him with a fire extinguisher from the car, and they escape to the building's parkade. There, they are attacked by Wang-i and Soon-ja; they bring down both zombies, but Hyeon-seok is bitten by Soon-ja. Knowing what will happen to him, he and Min-jeong share a sorrowful farewell until they discover that Soon-ja was wearing dentures, thus saving him from infection. They make their way up to the garage's roof, but Wang-i recovers from his battering and follows them, leaving their fates uncertain.
