Ten years later in South Korea

a girl named Mija is living with her grandfather and her pet super pig, Okja

Mija and Okja go around their home together to gather fish for supper

At one point

Mija tries to get Okja to cross a thin path, leading her to fall while holding onto a rope attached to Okja

Okja struggles to pull Mija back up

She runs toward a tree with Mija still hanging on

so that Okja may jump over and pull Mija up

Okja falls down into the forest, but Mija finds her in fine condition

The next day, a man named Mundo guides Dr. Johnny and his crew

to Mija’s home where it is at the top of the hill so they can find Okja

He complains about the long walk up the hill

and Dr. Johnny sees Okja and is amazed at how she looks

the grandfather brings Mija to the graves of her parents

He presents her with a solid gold pig statue that he purchased as he was unable to buy Okja

to expose the cruel conditions that the super pigs are subjected to

by a camera being placed under Okja’s ear

Jay asks Mija for her consent in letting their plan go ahead

Mija wants to bring Okja back to the mountains, but K translates that she agrees to the mission

In New York, Lucy and her crew view viral footage of Okja and Mija running through Seoul

They feel instant regret for sending Okja in there

K then admits that he lied about Mija letting them go through with their mission because he felt the mission needed to proceed as planned

Jay then starts viciously kicking and beating K for his deception, and he bans him from the Animal Liberation Front

The meat is later tested by special tasters who declare it’s the best meat they’ve ever tried

Lucy’s team preps Mija for her big reunion with Okja

Mija doesn’t want to go through with everything that they have planned for her, but Lucy’s assistant Jennifer shows Mija the kind of food Okja will become if Mija doesn’t follow through
