Homeless on the streets of Kuala Lumpur, Hsiao Kang is robbed, beaten and left for dead; he is found and nursed by Rawang, an immigrant worker, who lives in an unfinished, abandoned building. Rawang's feelings for his patient may or may not be sexual, but there's lust in the eyes of Chyi, a coffee shop waitress, when they light upon the recovering Hsiao Kang. And so a triangle forms as a blanket of noxious fog settles on the city and everyone has trouble breathing.
