Train To Busan

Plot Summary

Seok-woo, a fund manager by profession, isn’t able to spend quality time with his daughter, Su-an. On the eve of her birthday he plans to visit his separated wife in Busan to make it up to Su-an. Their co-passengers on board the Korean High-speed rail from Seoul to Busan include people from different walks of life – a CEO, a husband and pregnant wife, a group of high school kids, a couple of elderly sisters and a homeless man.

The train departs and the journey starts with the arrival of a woman who doesn’t seem normal at the first glance. With a bite wound on her leg, she definitely seems infected by the zombies. Immediately this woman turns into a zombie too. Seeing her, a passing female attendant tries to help her but the woman attacks her too. Soon this zombie infection starts spreading over to the other travellers. The first infected of the lot being the baseball team. But two of the baseball players, Yong-guk, his girlfriend Jin-hee along with two other students save themselves by speeding towards a front car. Before long, the news broadcast about the zombies spreads far and wide throughout the cities in Korea.

The next stop for the train is Daejeon, a town placed under military confinement, but it seems deserted by the looks of it. When the passengers try to get off the train, they realise the military personnel have been turned into zombies too. With no other option left, the passengers go back to boarding the infected train, but the zombies attack them there. Seong-kyeong, In-gil and the homeless man try to stay safe into a bathroom with Su-an. Looking at the dire situation, the conductor swiftly restarts the train to head to Busan.

Seok-Woo takes Sang-hwa and Yong-guk with him to find his daughter who is missing from her seat in the train. But he is chased by a group of passengers who are infected. Yon-suk and other survivors had locked the car door behind them to prevent the zombies from entering.

Seok-Woo and Sang-hwa try hard to keep them away while Yong-guk tries to break the locked door to stay safe. Meanwhile, Sang-hwa is infected and before he turns into a zombie completely, he gives his wife’s responsibility to Seok-Woo. One of the two sisetrs, In-gil sacrifices herself and turns into a zombie to buy more time for fellow passengers. However this completely upsets Jong-gil. Seok-woo thinks Yon-suk is responsible for Sang-hwa and In-gil's deaths because he refused them entry. But Yon-suk insists Seok-woo was affected by the blood splattered over his clothes.

Just then, Jong-gil sees In-gil as a zombie, blames fellow passengers for being selfish and angrily opens the door for the infected ones to enter and kill the passengers. But Yon-suk and an attendant are saved as they take shelter in one of the restrooms. Seok-woo learns that Busan is safe with a call from his employee. But he learns that one of their projects is responsible for the outbreak. There is an unexpected halt for the train as the rail track is blocked at East Daegu station. They find another train to escape but are attacked immediately. Yon-Suk throws the attendant and Jin-hee towards the zombies to avoid their attack.

Jin-hee is completely infected by now and bites Yong-suk who was actually trying to comfort her. After a huge ordeal, Yon-suk is saved from the zombies as the conductor finds and activates a locomotive on another track. By then Yon-suk is also infected and leaves the conductor to be consumed. While Seok-woo, Su-an and Seong-kyeong successfully board the locomotive, the homeless man sacrifices his life to save other passengers. But they see Yon-suk turning into a zombie and Seok-woo tries to fight but he also gets bitten and throws Yon-suk off the train. Seok-woo pleads Seong-kyeong to take care of his daughter and commits suicide by falling off the train to prevent others from getting bitten by him.

Finally, there are two survivors at the end of the blocked tunnel who walk through it and are spotted by soldiers. The soldiers question if they are survivors or zombies as the vision isn’t too clear. But just when they are about to fire, they hear Su-an singing. She continues to sing while they both are rescued from this unforgettable journey on the train to Busan.
