People who left, cats who stay.

In eastern Seoul, an apartment complex is soon to be demolished. Most of the residents left and the abandoned complex belongs to cats. To them, the complex is a heaven where food and place to sleep are provided. However, when the demolition begins, the cats' lives will be at stake. Residents who haven't yet left form an organization and start to seek ways to keep them safe. They hope their plans work but it's never easy to change cats' minds.
