Hei Yan Quan plot
After being attacked and robbed one night in Kuala Lumpur, Hsaio-Kang, a homeless Chinese man, is rescued and taken away by some workers from Bangladesh. One of them, Rawang, lets Hsaio-Kang sleep next to him on an old mattress he found in the street. Later, when Chyi, a waitress at a coffee shop, meets Hsaio-Kang, she lusts after him. As Hsaio-Kang slowly gets better, he finds himself trapped between Rawang, Chyi, and Chyi's female boss. In the meantime, a heavy damp mist sweeps over the city that stinks of the perspiration of its multi-ethnic population. These men and women and the old mattress get lost in the mist, but find each other.
