History
She and her sister Jong-gil goes on a train to Busan. She tries to make Jong-gil eat a boiled egg she cooked for her, but the latter refuses it. The two then watches television and see people hitting and fighting, what shocks everybody. In-gil then sees passengers from other cars running to this one to escape the infected.

Later, In-gil meets Su-an, Seok-woo's daughter, who accepts to let her seat for her. To thank her, she gives her candies.

At Daejeon sation, In-gil goes out with her sister and learns that the army supposed to help the passengers is infected too. Then she and Jong-gil run to the train but are separated when a zombie jumps between them two.

In-gil is taken into the train by Seong-kyeong and Su-an with a homeless man. On the restarting train, the small group is spotted by zombies who attack them and force them to lock themselves in the toilet. Seong-kyeong calls Sang-hwa on his phone to help them, which he manages to do with the help of Seok-woo and Yong-guk.

All together, they run to the car of the other passengers and the latter blocked the entrance, thinking that they are infected.

Seok-woo, Yong-guk and the homeless destroy the door and bring in their friends except Sang-hwa and In-gil who let themselves be infected to save them. In-gil then appears like a zombie, which causes Jong-gil to drop the zombies on the passengers who caused the loss of her sister.
